The difference in strategic risk between minerals and fossil fuels is that if prices spike you don't need to buy. OPEC controls the world oil price and can send inflationary shockwaves around the world, and yet here we are saying "better be cautious about China processing those minerals".

I live in Canada and we are just starting to get into this mineral production. I feel like we dropped the ball a decade ago and doubled down on oil rather than investing in mining development. Now we’re so far behind countries like Australia and we’re scrambling to catch up.

No, actually, in the 70s, we were one of the largest cobalt suppliers for cancer treatment, but it was too environmentally damaging so we shut it down. Now we don't care if we destroy the planet as long as we feel good about it!

Very good, even handed and accurate presentation. One thing worth mentioning: the real concern about lanthanides (the real "rare earths") is their MILITARY applications, not their cleantech applications which all have substitutes. Furthermore, getting rid of fossil mining (or at least reducing petroleum mining greatly, eliminating coal mining and nearly eliminating gas mining) will dramatically reduce how much actual mining goes on here on earth. The transition not only allows substitution that the fossil fuel paradigm fundamentally was incapable of, but also will result in less mining and a near elimination of resource destruction- all the cleantech applications of "critical minerals" allow recycling- they don't dump the product into the atmosphere at end of life.

I've got one coming up on mining in general and how to make it zero emissions. It's crazy to me that we keep hearing how the energy transition will require six times as much mining... That's true for minerals but conveniently leaves out that HALF of all mining today is for fuels! So far less mining overall and as you point out that's only in the short term. In the longer term there should be very little as recycling takes over from extraction.

Heron Fundamentally the U.S. needs fossil fuel and if the U.S. needs it so do all western nations. The U.S. declared bankruptcy in 1971. Then the U.S. dollar was saved as a global reserve currency because oil became priced in dollars. If the west ends oil then opec will join the BRICs and sell oil priced in yuan. You’re effectively destroying the ability of the U.S. to offshore inflation. If you stop oil you end the ability of endless government growth or endless war and bank bailouts. Even Canada or Australia won’t give up their bank power to bailout their banks or prop up their real estate. Wake up and smell reality.

If you are involved in the mining industry, maybe you can set me straight, but it seems to me that electric would be great for mining because it doesn't generate fumes in tight spaces underground and mines are (relatively) static places so you can build infrastructure. And as for mining-related transport, we can electrify trains relatively easily and having rail sidings at mines seems like a no-brainer if they are moving a lot of materials and equipment.

The drills normally run on diesel power to move around and 1000v power while drilling. This EV version is not capable of 'traming' very far - one to two levels at most. This may work in some mines, but not all of them, as most have their workshop facilities on the surface where logistics and manpower is better and diesel machine can easily travel to. For the loaders, Sandvik is also trialling EV versions, but not in the capacity sizes used in Australian mining - move more with one Machine = more profitable enterprise. Electric Underground trucks are a long way off for decline mining, due to the travel distances and power required to move the 65t load plus the truck up a 1:7 decline slope for 6 or 7km of roads. The current Volvo power plant is a 567kw. They have a battery variant available, but it is suited to tramming in the levels and dumping underground into ore passes rather than hauling to the surface. Both the loader and the truck have a battery exchange function and could be used as short haul units, but they are more costly to purchase and then need banks of batteries on charge for the fleet. In addition, we all know the risks of a runaway battery fire, now try to imagine how that would be when you are in the same underground location and breathing the same air with that battery pack and all you have is a respirator mask you need to quickly put on and make your way through the smoke to a refuge chamber...

Open pit mining excavators and face shovels can be plugged into grid power, and surface haul trucks can use a pantograph system if they are following a set route, and maybe have very limited battery capacity to drive 'off course' away from the high voltage power. Underground drills run on 1000v power already for drilling operations, but use diesel engines to tram to different locations around the mine (and surface workshops, fuel bays etc) There are battery rigs available and our company has some, but we're still carrying out risk assessments for they due to the massive battery packs and the fact that workers share their breathable air with these machines. Some U/G trucking and loading operations on single levels could be set up for the latest battery pack 'swap and go' machines, but not for regular mining operations where locations constantly change during a shift and trucks run up a 1:7 incline for 30 mins carrying 65t of dirt. All of the above also assumes that the incoming mine power supply is endless. Most mines are out in the middle of nowhere and the power supply infrastructure was chosen and supplied based on a known projected future energy requirement. (The remaining energy accounted for in diesel) To suddenly replace all of the diesel with electrons would in some cases, require changes right back to the initial point of supply. I'm no 'fan' of diesel, having shared the U/G air with the machines for years, but there is no simple economical quick fix.

The whirlwind will segregate the particles, according to their specific mass densities or weights, into free-floating ‘Saturn Rings’, of separated elements. After these floating particles rings are fully separated, chutes pop up to catch the rings and shunt the particles into separate bins, so that they can be easily recycled. EOJ

Not dangerously dependent but foolishly going down that road, we can still use fossil fuels for transport (China does use carbon and is the biggest polluter at 29%, US 20%, Australia just over 1%, UK less than 1%) and new nuclear along with renewables when they are cheaper and widely available not when we are going to be dependent on another dictator country, we all known what is going to happen in that regard. The imposition on dates for renewable energy transfer is a false construct and will increase prices to an extent to ensure that the COP (Out) plans will not work. Hosting the COP climate change in Dubai has shown that the carbon producers (Who had the biggest delegations in COP previously) have taken control of that enterprise and the deleting of carbon to be phased out from the charter confirms that (Although carbon will in actual fact be used up until the end of the century anyway it was unrealistic to think that it could be totally replaced). The transition from Carbon to Renewables (Not Green as some of them are green only because they are so toxic!) Should be carried out as like with horse and carts to steam and then petrol by economic factors only, not by political intervention on prices, this is having a backlash as it's unaffordable by the majority. For example my old back boiler packed in (30 years service) and it was replace that with a gas boiler, £2,000 tops, or have solar, battery back up, insulation and an air source heat pump £60,000), so funny enough it was replace the gas boiler, later on I will insulate the outside walls internally (£3,000) and it will never pay me back to go "green" in the remainder of my lifetime!?!

Great summary! Seems we are in good shape with Lithium until at least 2027, and there are lots of options for other critical minerals. Australia could certainly make a play to refine the many minerals it already produces.

1. By decentralising energy generation via microgrids (and installing them closer to the demand centers), we can defer the transmission grid upgrades. 2. Front-of-meter energy storage is essential for such microgrids. In this case, redox flow battery can substitute lithium-ion battery. There are 2 options for RFB: Vanadium and Zinc-Iron

So nice to see someone who actually know what they are talking about. I get very irritated by people talking about rare earths in batteries when essentially there isn't any (there is one LFP supplier that puts a bit of Yterrbium in). And rare earths not being rare, and lithium not being rare either, and more coming from Australia than South America and so on. And cobalt all being mined by kids (when this has already been pretty-much stopped and was never more than 1% of supply). We have enough things to worry about without people just making random shit up and then arguing about that instead of real issues.

Hi Rosie, probably the biggest issue with the clean/green energy transition is that it is almost completely viewed through a first world lens. What about the citizens of less wealthy countries, I'm sure they would like all the mod cons we have. A prime example are electric vehicles, these are a first world luxury because they are expensive and use large amounts of "critical minerals". I know that many people believe there isn't a critical minerals crunch and that there is a lot of copper on earth and rare earth minerals aren't that rare. However, most of the low hanging fruit regarding high concentration mineral deposits have been exploited and mining lower grade deposits is more expensive. At some point the economics won't make sense and who wants the pollution and environmental issues that will come with a huge increase in exploitation of "critical minerals". To replace all the internal combustion engine (ICE) vehicles in the world with electric vehicles using copper wiring and rare earth magnets would require significantly more copper than is present in ICE vehicles and where will it come from? I know that there are other alternatives to electric motors using copper wiring and rare earth magnets one example is an induction motor with aluminium wiring. However, the resistivity of aluminium is lower than copper and larger wires would be necessary. A benefit is that induction motors could potentially be lighter, but they would be bulkier and would be less powerful per unit volume because the same current densities achieved in copper wiring couldn't be reached before melting the wiring. Another huge issue I haven't heard mentioned or discussed is that electric vehicles are a tremendous waste of valuable minerals. I doubt the majority of car owners use them for more than 3h a day. If we are generous and say 4 h that corresponds to a vehicle being idle for approximately 83% of the time. Those resources would be better used for generating renewable electricity from sources can operate at a rate > 17% of the time. And this is not to mention electric cars usually have 2 or 4 motors compared to a possible electric motor cycle. We should consider producing liquid fuels from renewable sources such as biological waste streams, cellulosic biomass etc and live with the energy penalty. The resources that would go to electric vehicle could be put to more productive uses to offset the liquid fuel energy penalty and wean us off fossil fuel use for other applications. We have to remember that we can't sit in our first world ivory tower and need to consider the aspirations of all. Ideally nuclear fusion with cheap and plentiful electricity would come to the rescue, but as it is said, nuclear fusion is always 10-20 years away. Best regards, Dr Beavis (organic chemist)

As a geologist, the frustration I have watching our raw materials shipped overseas for processing and then use, only to come back as finished products is extreme. Mobs like Lynas tried so hard to both mine and refine RE ore in Australia, and was eventually forced to export and process it in Malaysa. We have huge Li deposits in Western Australia (WA), predominatly as pegmatites, and we are lucky enough to have production of technical and chemical grade lithium products produced. Given WA's vast landmass rich with green energy sources and raw minerals, refining, production and manufacturing of high-end good should be very high on the To Do list for the State and Federal Government's. I'm sure other states have similar opportunities that could be with a bit of political will and spine.

One thing I always wonder about is Power to Gas. You can always take excess solar and wind and store it as hydrogen - then use it for fuel later to run generators. You don't need any special materials for these energy storage systems. All the parts are pretty standardized and obtainable.

I wonder how much of the copper shortage was alleviated by Aluminum wiring. Long-distance transmission lines tend to be Al instead of Cu. When we got our ~40 year old electrical panel replaced: we were able to upgrade to 125A service from 100A service because #0 sized Al (rated for up to 135A) was used for the supply, instead of #2 Cu (rated for 100A) (due to a copper shortage in the 70's). New installations are supposed to have 0000 Al cable (rated for up to 205A).

Most excellent, Rosie. Thank you.

Don't forget copper! Very important in electric cars, and especially important for the power grid. It is estimated that global production needs to go up something like 5X what it is now to fully decarbonize.

The reality is that copper mining is is generally mined as low grade/high tonnage operations. Most of these large operations from initial discovery through to first production has a time-span of about 15 years. Proving a deposit is expensive. Getting the project permitted is a lengthy process depending upon the location. The recently shut down Cobra Panama operation was a US$10 Billion development which was processing 80-100MTPa at an average grade of 0.4% Cu. The 15 year timeframe is not negotiable. And that's for each and every large-scale operation.

Well done. Deeply appreciated.

Good that you are visiting mines where it all begins. Would like to see the processing details.

Nice all the information regarding critical minerals...Alot of love 💕 from India

Thanks for the informative video Rosie it was very interesting. Following on from this and if you are able, it would be great to know if you could do a video on the end of life processing (ie recycling) of these manufacture products that contain these minerals because to be fair I believe that these too are another major challenge with the energy transition that isn’t being properly dealt. Cheers, Matt.

I was surprised to hear a lot of the high-quality graphite used in batteries comes from oil! And the UK has one of the leading processors of this graphite. Would be interesting hear your thoughts on this?

Major discoveries of Rare Minerals are recently reported in Minnesota and Wyoming, underlying lignite. It'll take a decade to develop and a decade to build the processing.

First, thanks for reminding people of the correct definition of rare earth minerals. I get a little twitchy at times when I hear some less that accurate use of the term. I know that for many of these things increased supply, as well as source diversification, is critical. I wonder how much this could be eased by robust recycling practices? Certainly that won't solve the problem, but it could somewhat ease the transition. As with every aspect of human existence, being efficient and mindful with the use of our resources is mandatory for our long term well being. Wonderful video, I look forward to seeing more along this line.

Thanks, Rosie. Another great explainer.

Thanks for this excellent information Rosie.

You don't have to deny climate change to see there are some real problems here. There's good reason to believe supply shocks are likely. While it's good that we see law-makers trying to close the gaps, no amount of written law will overcome laws of nature. Prospecting, mining, refining and processing the necessary inputs takes time to develop. To make a substantial green transition within 10 years is going to require unprecedented new developments.

Outstanding video - thanks Rosie. I value your bullet point texts & images reinforcing your explanations. As ever, I appreciate your rapid yet clear explanations.

As an engineer, I enjoy your videos.

Over 30 years we are processing ore from 3-4 % and now 0.02% is viable but requires exponential increase in energy to process which can only be done via fossil fuels at the moment.

Going up the value-added production-manufacturing chain is key for Australia. As is usual, government policy, support and vision is essential. Overall I am optimistic that Australia will be bigger in the world economy in the future. Immigration will be important to our future. Love your videos. Cheers.

6 times the ampunt of holes in the ground (and process energy, and water use, and biodiversity impact)? If this is a "transition to clean energy", could we refine the very definition of the word "clean"? Thanks for your amazing videos - it is refreshing to hear a technical expert challenging the status quo (and technocratic view) of the mineral industry.

9:52 If you want to scale up mining and purifying minerals by a factor of six, you will need a lot more energy. Can we double mining, shipping and purifying those minerals, without using more diesel? Or should we stop flying and use the jet-fuel to get the minerals we need out of the ground? I'm not a "climate-denier". But you seem to ignore the amount of energy that is needed for the energy transition. Can you please make another video explaining where we can possibly get the diesel for the sixfold increase in mining?

We farm 50% of habitable land. We have mined (working and out of life mines) less than only 0.1% of habitable land. We have more than enough land to mine to satisfy everyone's needs.

Minerals aren’t evenly distributed, though, and not all land is suitable for mining.

The problem is not only that it runs out but how much it costs and will cost to remove them, something that is already happening with copper, which since 2000 has tripled its price. Also do not forget that if global growth continues to rise steadily it will be exponential. And the calculations change completely

Very well done.

Very informative, thank you! I'd like to know more about copper. The bit of news I've seen and price hikes with anything copper related the last few years is a bit worrisome. But perhaps it's overinflated?

On the other hand, mobilizing the capital for a rapid build-out of copper etc mining and refining capacity is proving to be difficult. The issue is not whether reserves and resources are sufficient.

excellent video Rosie!!!

once again the supply of copper does not look equal to the demand for upgrading grids and adding the interconnections needed for dispersed green energy generation. Might Rosie take a look at this?

Just found out this video, thanks for your expert take on this, now I feel I have learned a lot more. I am actually excited about new ways we discover how to store, transfer energy, as it will change our lives dramatically. Also I really like how you underline gradual improvements which is how you get to high efficiency, but those can't be forced, they will take time. As for us running out of time....we will. There is no way we not gonna overshoot it. Question is by how much and can we be able to work with it. Hard times ahead, but as one book says "lets science the rare earth out of this" 😅

Look up Simon Michaux's videos. He has done a great deal of work calculating the volumes of materials which will be required for the energy transition. For copper, the amount is equivalent to 189 years at the current rate of production. Nickel is 400 years, Lithium is 9900 years. Graphite is 3288 years.

@@st-ex8506 I don't think he is over-estimating the storage requirement. I have looked at the case of 6x wind + 3x solar (i.e. times what we currently have in Australia), and you can potentially have two weeks in winter with big deficit which can only be made up by huge storage - or something like gas turbines, which means you are no longer 100% renewable. And there is a significant cost to have such a large number capacity in turbines which you only use 2 weeks a year.

@@frankszanto People like RethinkX have simulated, based on real weather data , how much storage would be needed. And even for New England, a region with pretty unfavorable winter weather, they came with around 90 hours of storage. Other teams come, for the world average, to numbers between 60 and 70 hours. These numbers make storage very affordable, at 1-2 US cents per total kWh consumed. Michaux uses 2 MONTHS! He is more than 10 times off on one of the key parameters!

One thing that annoys me is that critical minerals often go into stationary battery solutions. Why use Lithium for home and utility batteries? If it has the energy density characteristics to sit there and not be mobile at all, and it's affordable, safe and long lasting, then it's a perfectly good stationary battery chemistry. I sincerely hope sodium ion can fulfill this role without too many other rare minerals. I don't care if my home battery is the size of a garden water tank. Truly. Makes it harder to steal even. Stationary batteries are as important for tackling climate change as EV batteries. Especially when you consider that stationary batteries compliment renewable energy and EV charging infrastructure very well.

I would assume that the children there would continue to get exploited regardless, if not mining cobalt, then for something else.

I would like to get your point of view on future availability of copper.

Sounds like we’re on track for a repeat of what happened to the opinion of the early 1900s copper expert that copper extraction would cripple electricity-based society in a couple decades. That didn’t happen, and, so long as we keep actively working towards developing supply chains, neither will critical mineral doomers’ worries.

Thorium Energy Alliance tried some years ago to set up a "Thorium Bank" to capture the radioactive waste stream from rare earth mining inside USA, since the reason USA doesn't mine them is because of nuclear regulations, not a lack of supply. It blows my mind it didn't get off the ground considering the supply chain risk they have.

I think Rosie should have left this video to the geologists. Will we run out of copper; no it's going to just bloody expensive. Chile’s average copper grades more than cut in half between 1999 and 2016, from 1.41% Cu to 0.65% Cu.

When more development happens with phase change technology with solar vacuum tubes implemented as energy capture = this will easily lighten the load on mineral extraction- this works best on back yard situations - high density black sand that is abundant around the world and easy to gather = makes a very good thermal battery

The world reserves of fossil fuels have been "running out" to my personal knowledge for at least 50 years. What is actually happening is that places and/or sources that are more difficult to exploit come into play as the economic demand and technology develop to exploit them. And that's just oil. When the British coal industry was destroyed by the Tories in the 1980s and 1990s by weakening the Miner's Union until cheap coal could be imported in bulk from Eastern Europe, there were many British coalmines with estimated reserves of 300 years... they're still there!

Yeah the processing of rare earths only can happen in China because their environmental regulations allow for it. Since rare earths are often found with uranium, I wonder why we don't mine it here in Canada. We have always been one of the biggest suppliers of uranium in the world. Surely the tailings piles at our mines could be processed for neodymium or other rare earths without contaminating another location. I think that China is likely making better use of the rocks that they are mining by processing them in multiple ways to extract multiple kinds of minerals

The only thing hindering the transition to solar/wind and batteries is the cost. NG, coal, and nuclear is just cheaper. That's what it boils down to. Money. You can't artificially prop up green energy and expect it to succeed.

It's not just climate change deniers that are saying that there is access to insufficient mineral resources to satisfy the proposed scale of battery production. Simon Michaux talks about the practicalities of mining the required minerals such as lithium and concludes that it's likely unfeasible. He was commissioned by the IEA to provide the feasibility research, so would hardly be considered a climate change denier. There is so much more to mining than looking at the probable and possible reserves. A basic understanding of mining will recognise that it's energy intensive and also takes time. Time that we don't have if we are to meet the deadlines for net zero. Renewable energy such as wind, solar, wave, hydro all take time to produce the energy at their steady rate of production(there is also non producing time). Where is the huge amount of energy to mine the minerals coming from? It's like using a chisel to dig holes for tree planting and telling someone that they are anti-tree planting when they sensibly suggest to use a spade instead. There is a climate change problem but the current way we are going to address it is a kin to digging with a chisel. Companies like janus electric and the x-bus team are putting resources into user removable EV batteries which will allow users to only take as much battery capacity as needed on each trip. But no one is listening because big EV players are promoting the frivolous use of excessively large batteries regardless of trip distance.

Thanks so much Rosie! I'm loving this series. The doomers in my blogosphere are really banging on about running out of minerals etc. I also enjoy the footage of the stuff being extracted as a raw resource and then processed etc. Anyway, question. If we were to 'run out' of copper as they so hysterically assert (forgetting various economic feedback loops and recycling etc) - what about this next claim? Aluminium - which is 8% of the earth's crust and more abundant than even iron ore at 5% - could substitute? I'd love you to chat with some industry insiders and technical people in EV's and what-not about what this would take. That's WITHOUT doping it with graphene and whatever people are working on to make 'superconductive aluminium.' Just bog standard aluminium with 60% of the conductivity. How would we do it? This is the claim. Just use more! "This means you will need a 25% thicker wire for the same results. However, the aluminium in this equivalent wire will cost and weight about half as much as copper. That’s it. Aluminium in power lines? Of course! Also underground! And in transformers and coils, in motors? Yes!" He claims over 90% of the roles of copper can be replaced with aluminium. I'd love you to either mythbust this one or confirm it with some electrical engineers - car engineers - wind turbine people - etc! www.shapesbyhydro.com/en/material-properties/how-we-can-substitute-aluminium-for-copper-in-the-green-transition/

There is a wide gap between what we want to happen and what is actually possible though. If we need to ramp up 6x faster we need to realise that is unlikely due to not enough co-operation, human resources, capital and the other inputs. It is hard to see a solution that does not become authoritarian in nature to meet such a steep increase in demand. I.e. forcing people to study engineering to address that shortage, forcing companies to co-operate (e.g. sell x to ABC pay ltd for $y/unit), forcing government to issue capital for such mines meaning government holds the risk of return. Unless we can think up new ways to solve the input constraint sensibly, we aren't going to get close to what is needed unfortunately.

The sea is full of extractable sodium, the earth has abundant extractable sulphur. It is only a matter of time before the rarer metals are reserved for special uses, instead of disposable 'vaping' products.

Hubbert's peak theory of mineral extraction, led to predictions of oil production, peaking in the 1970's. And the theory is still accurate, so what happened? Technological advancements such as fracking, made it a second order factor in oil production. Which is why long-term predictions about mineral production, tend to be, so inaccurate. And are government subsidies. such as the US. IRA sustainable? So nice overview on an important subject, (even with the clickbaitish title). But would love to hear this discussed among a diverse set of disciplines, including some fellow economists, in a future post. Rosie good luck with your new position.

Mining is always detrimental to wildlife and its habitat and as wildlife is already under extreme stress from human overpopulation our extractive economy, we need to reduce the need for mining altogether, such as in closing the loop through mandating 100% recycling. Whatever we have here is found on neighboring extraterrestrial bodies, so we really should look at mining the moon, asteroids, etc. And, if we increase efficiencies then we need less power to start with, which may require more of these critical minerals and elements.
