@46:28 making the video might be worth making, just for the sake of a video. i would watch it.
New to this, but wouldn't be easier if you cemented the copper out?
(Freestyle Libre 2 Sensor ) has some beautiful little (Gold Plated board ) that is a lot of gold just being thrown away………Whenever you get your hands on one, pilled the plastic away and you will see those beautiful little Gold Plated Boards 🤩🤩🤩🤩🤩🤩🤩
I recently learned about the glucose ( freestyle libre sensor patches ), my wife wear them…….She changed them out and throw away, I took one of them and pilled the plastic back…….Discovered some beautiful little ( Gold plated boards inside ) ……These little sensors are just going into trash.
Cheers brother looking forward to the next episode
Approximately... 5:05 to 5:15 YOU SAY, WRITE IT DOWN. Then YOU immediately ! Forget to write down weights. As You Are Weighing The Items You Are Using. I.E. once again... PROVING YOU ARE, JUST SCREWING AROUND !
IT'S NOT COMPLICATED... TO MAKE COPPER -Anything !
The difference between. Science & Screwing around is. SCIENTISTS ! KNOW WHAT THEYRE DOING. You Are Just, SCREWING AROUND...
I think I prefer that title “what is this? Part 6
I have a question. I've used copper to drop silver, I've used lye and sugar for silver chloride, I recently used a piece of aluminum and a bit of sulfuric on silver chloride, I like the aluminum process, what are the drawbacks to using aluminum? There aren't many videos on this, I absolutely do not like the lye and sugar method.
So in short you boil the sulphuric acid. Distilled it and that produces Nitric acid
Looks great. I do a lot of industrial scrapping and nickel is a valuable metal that we separate out. The alloy in our material is only like 20% nickel but I know that’s what my buyer is looking for “Ni-resist cast iron”. I wonder if there is a good way to separate the nickel from the copper? So if you SMB’d into a large bucket, filter the gold, then place in bucket with copper to get all your trace precious metals. Then place in a bucket with pure nickel in it. Wait for copper to drop out along with any possible tin/lead. Then you should have a solution with nickel and iron. Switch to a clean cementing bucket with iron in it and finally drop the nickel. Maybe. I just don’t know how long of a process that would be.
Hi mike this waste solution as there still active componant would have been possible to dissolve ic pins in it ? You know to use all possible ingrédient and save some $ ?
Looking forward to part 7
Woo hoo! You used my suggestion or at least came to the same conclusion lol. Referring to using water to dissolve the sodium chloride in your solution
Get that gold! It’s nice that gold like to precipitate from a more dilute solution than palladium (which would rather precipitate from a more concentrated solution). Should be easy with some SMB straight into that bucket, let settle, and decant. Thanks, Mike, for bringing us along on this adventure.
Mike, in the hope that you still see new comments on older videos, here's my recommendation about skimming slag: Get yourself a long, BBQ-cutlery-type (shallow) spoon to skim the slag off of the top of your crucible. A Professional foundryman has a channel called "Windy Hill Foundry" here on KZread. He (Clarke Easterling) uses that type of spoon for skimming/dragging slag off of the top of his melted iron (old disc brake rotors) before pouring. He (or his helper) then often pours a spoonful of some type of powder on top of the gate opening. Of course, he usually casts into full sand molds to make products for his customers who usually provide a pattern to him, which you aren't doing, so I don't know if pouring the "powder" on top of your "loaf mold" would help you or not. Clarke also uses a thermocouple of some sort to measure the temperature of the melt to ensure that he will get a good pour -- maybe this helps avoid gas pockets, and probably "cold shuts" (if that's the proper term for the metal freezing before the mold is completely filled) too.
Since purity of each ingredients would probably vary by brand and/or country, what would be the best (or easiest) way to find the best ratio of each ingredients to reduce losses?
Those bucket vacuum are super cheap/unreliable... You can make a better one by using a normal 5 gal bucket and adding some fitting on the cover. One for the funnel and an another than fit the hose from a regular shop vac
Recover the gold
Awesome video. Look forward to the next
considering you are doing this as a method for somebody else who has a lot more of the material you should go after the gold so he has an idea if it is worthwhile for him to go after it and how much to expect
Recover the gold
Wow. This has been an exhausting experience, and I'm just WATCHING the process! Mad props and much respect for the amount of patience you have 👏 Looking forward to seeing the final results. Mental note to self, NEVER work with palladium, unless I need to drive myself crazy😁
Mike, do you work as a Chemist, Chemical Technician, or are you just an chemically experienced "enthusiast"? :) Also, when I visited a few weeks ago, I didn't think to look at or ask about your "fume hood system" layout. Does the exhaust go somewhere that any "heavier than air" fumes/gasses won't fall back down to where you are working? Before I retired I never paid much attention to the total fume hood systems in our Materials Lab (which included a lot of Chemists & Chemical techs, along with Metallurgists & "polymer experts" (I don't know their proper title) and I don't recall much about the fume hoods & scrubber systems in our Chemical Cleaning, Electroplating, & Conversion Coating Shops.
Self-taught chemist. Got interested in chemistry playing around with large amateur rockets in my 20s and 30s. Eventually gave up that hobby (I had too many and something had to go). Got into e-waste refining in my 50s and had to learn much new chemistry. Less likely to blow myself up with this hobby, but poisoning is always a possibility. Fume hood is home-built. The first iteration had a stack that went straight up. Found out quickly that was a bad idea since most of the fumes I make are heavier than air and fall right back down. Now I exhaust it at ground level in the side yard. Just a small patch of dead grass around the exhaust.
XRF analyzer sitting at Dulles airport customs. They forgot to mention that I had to pay the tax and duty.
They forgot to mention that they are in another country and you are the importer? They deal with the country they are in and you deal with the country you are importing the device into. They didn’t forget shit, import duty is on you. Don’t blame them for not know what they are not responsible for in any way. You should really take the time to understand the law you are dealing with
You wanna trade me a xrf anlyser? My email is on my channel.
Hi Mike, So much chemistry - my head is spinning! Certainly looking forward to part 7! Finding gold is a wonderful bonus! Stay safe! Thumbs up! Jim
Thanks for pointing out Hoke's book being available in print! I've been hunting for it for over a year now and no luck at affordable prices. Got it ordered now :)
If I'm not mistaken you need to rinse PGM ammoniumchloride salts with saturated amoniumchloride solution in water else the PGM salts can dissolve.
Regardless how saturated your solution is it will still desolve some of the salt. All pgms are a bitch to work with period!!! That's why no one else does this😊
Oh sh first😂
Just what i want to do, been planning for years. Honeycomb grid.
You mentioned hcl to dissolve the tin is there a way to drop the tin back out of solution?
I think that solution is saturated.
I agree Glassware cleaning is a pain I have to do it a lot,that’s the only thing i don’t like about refining
Mike, I'm very glad that you decided to wait for the very hot beaker to cool off before adding water or anything else to it. Some years back (10-15? years) in the Chemical Cleaning Shop where I worked, one Artisan made the mistake of adding too much water, too fast, to a ~100+ gallon (~3785+ L) tank of a very high-temperature jet engine cleaning solution (I don't recall what it was). The solution/water "mix" immediately "inverted," trapping the water under the chemical solution which was well above the boiling point of water. Fortunately the Artisan had walked a short distance to the side of the tank for some reason. The water boiled & flashed to steam, ejecting at least half of the tank's contents from the tank. If the Artisan hadn't walked away from the tank (without even realizing the danger he was in), he would have been very dead in a very painful way. He was given free leave to go home for the day and quit shaking from that incident.
U suck at siphoning.allways pull gold off the bottom. Now I pour through a filter and put the filter In the container for later
I just found your video 7/16/24 and liked it. In 2022, I bought a lot of lab ware and gear, a 2 burner furnace for smelting, and a desktop jewelers electric furnace. I have around a pound of mixed Sterling silver scrap and around 10 ounces of mixed k gold and some electronic scrap I was going to refine. Then my wife had a stroke and passed away, I sold our home and property in May of 2023, and everything is in storage. I was setting up to capture the nitric acid during the inquartation of the combined silver, gold, and base metals parting process for reuse. I now live in an RV and can't use all that new stuff that is scattered around in 2 large storage units. Including the metals and silver smithing and jewelry making equipment. With 2 AC to DC rectifying units for electrolysis refining. I had planned to create a Utube channel and have a few aftermarket gopro type cameras and mounting brackets. I do have dry chemicals and 2 large bottles of nitric acid at a friends house. I'm around Casa Grande Arizona. Is anyone interested?
that is why I never loan my presure washer,, How dumb to run a high pressure pump without water passing through it,,, $300 and some change buy a new one now...
awesome video, I made a propecting video too in my channel and if anyone can take a look at the river where I prospect, Im not sure how to use my sluice since the river is flat.
Wow, sorry you had to go through this. I would separate liquid from salts . Then try your solubility idea.
Oh boy thats a cracker. (how to get the sodium out)
What is the saturation limit of salts in hydrochloric acid. Look at the volume of liquid you started with. It stands to reason you would need as much to totally dissolve the salts again then reduce to form chloride salts.
Why not just add a cup of distilled water to it so the sodium chloride will dissolve easier
Wit until the next episode.
Can't wait to see how it turns out. Is this a case of maybe doing smaller batches would work out better than trying to do everything all at once?
nothing but a mess
Rest in pieces little beaker. Thanks for the interesting experiments as always Mike!!
Kinda eery watching this. I know you're well aware of the dangers of platinum salts, and you're using some PPE. But that would freak me out. Love your vids though Mike!
I think you carbonated your palladium into palladium pop rocks candy lol
Hi Mike, "but then serious drama ensued"??? What? NO! not with Mike!! couldn't be.... ooppss..OK maybe a little drama... Here's my 2 cents...Could you take the beaker of green/brown sludge (very technical term) - pour it into a 5 gallon bucket (or one gallon bucket), break up the lumps, then add the Sulfamic acid solution and let it bubble & fizz! Looking forward to seeing what you decide to do! Thumbs up! Be safe! Jim
Hi Mike! I have zero experience with PGM's. (Sorry if my idea are dumb😅) If NaCl not soluble in HCl maybe you can use a stick blender to blend the salt and rinse/boil with HCl? Then test the salt if left any Pd in it?
