Hi sreetips. I would love if you would discuss the costs you incur a little more. I know this is a hobby, but as prices change, it would be nice to hear about how much you would spend in chemicals on a process like this. I think it would be good for other would-be refiners to get a better idea of what they could be getting into.

Nitric is $50 for 2.5 liter bottle. I used about ten bucks worth. The scrap was $130 per pound. Hydrochloric is $12 per bottle. I used about two bucks worth. SMB was three spoons. Maybe fifty cents. So if your goal is to buy the scrap and immediately resell the recovered gold to gain more paper dollars (profit) than you started with, then forget it. My goal is to create content for my KZread channel. I was glad to find a source that had that much scrap available to buy in one spot.

Computer scrap is very popular because of the belief that it contains much gold just waiting for those who can figure out how to get it. That’s just a myth. Electronics contain gold because they’d quit working if they didn’t. But it’s just trace amounts. The real money is in scrap karat gold; broken chains, bracelets, rings and necklaces. With gold so low, people are clueless about it. They believe, incorrectly, that paper dollars are more valuable than gold (and silver). This misconception has created a gold and silver buyers paradise. But some folks are starting to catch on. We’ve notice a steep decline in the amount of metal that can be found. But it’s still out there if you know when, where, and what to look for.

No, I tell them that if they don’t need the money then they should just hang on to it because precious metals are trending up while the paper that about to pay them is going down. But that rarely happens. When they hear the amount that I can pay for their scrap, their jaws drop open, and they immediately take the cash, unmindful that the paper I’m giving them is declining and losing value faster than a snowball in July. In that sense, it’s phycological because they believe, incorrectly, that paper dollars are more valuable than gold (and silver).

Seeing the gold foil separate so beautifully, I would just dry the gold flakes and display them in a clear glass vial so they can be admired 😁💛 Although I have to admit, the gold button is beautiful 🌟

Another splendid and didactic refining video, what a pro!

I use a slow process that soaks fingers and pins in HCl with just a little copper chloride, called the 'AP process'. It's cheap and you constantly generate more CuCl2 reagent in the process. I can just throw everything into a beaker and forget about it for a week. Doesn't even need bubbling. Just stir it well every few days. When white CuCl crystals begin to form and there's still base metal remaining, just pour off most of the concentrated waste and add more HCl. It works VERY well for pins. Nothing but foils are left over. For fingers, you still end up having to wash the thin gold off some of the cheaper, modern fingers. The old types do tend to fall off nicely.

A really beautiful little button and fascinating that this was a quicker process. I've watched a few of these from others and it's always been a much more involved process. Gold, silver, precious metals and gems does interest me and not necessarily just because of its monetary value but the beauty of those items. 👍

That is impressive! It went from taking months to same day service. Less waste solution to deal with as well. I'm convinced!

I know you most likely lose money when you make a computer scrap video, but it's always a good watch & wish you'd do more of them. Maybe next time you could do similar technique on different computer scrap, like gold pins. This is the way I'd want to process my computer scrap when I start to do it. I wouldn't care if I lost money because it is a hobby & hobbies usually cost money!!

Nice fast job Sreetips, much quicker than many other methods, it’s all about time and effort really!❤❤✊

As usual a great gold processing video from sreetips 👍🏻

Superb ! That was way faster than anything i ever tried ! If you recall the Weir Effect thing, it'd be great to do the Nitric treatment in a glass cement-mixer. Adding a bit of water/nitric as the thing turned, at an angle, the gold foils would flow over the edge. Mostly they get trapped by the circuit boards, as you saw. AR directly on the FR-4 circuit board material could well have produced some things you might not like.

Most of us ewaste scraper know there is small amounts of precious metals in electronic. As the saying goes "It takes alot to make a little." Some resell computers components or separate gold fingers for sale, like what sreetip demonstrated here. Some, like me, tear down, separate, and stock pile metals to turn in for cash. Metals found in ewaste are steels, copper, brass, various aluminums, tantalum, PGMs, silver, and gold. I thank you Sreetips for knowledge you're sharing. I have learn new better cost effective ways to process precious metals. I even started to buy and collect jewelry to increase my precious metals yields.

Love these vids

Excellent video

You make it look so easy Mr. Spiteers

Thanks for sharing. I like refining e waste, guess it's the mystery on the yield that's addicting.

On those boards, it tends to be the copper layers where pretty much all the metals are attached unless they are bolted/screwed to the board. Going right after the copper seems to been the easiest way. If you get a large enough batch and can cycle through large boards and not just trimmed then you could recover a fair bit of copper and silver this way for basic refining to recoup some costs. Copper would be the highest yield volume wise. Even the cheap boards like in basic electronics would give up copper in the least. Silver could be in the contacts and solder at the low end. Good for a hobby unless you needed fine powdered copper/silver for maybe plating.

Here's an idea. This would probably be on the same lines as recovering gold from gold fingers (not profitable and maybe even LESS rewarding), but maybe fun for those who are hobbyists, or just plain curious. There are trace amounts of gold 'almost' everywhere, if you know what to look for. Your neck of the woods is no exception. Have you ever thought about going to a local creek, or stream and digging up a couple of bucket loads of dirt and gravel, from lower lying areas to process? Panning only reveals visible gold to those who do that. What about the gold that is too small to see, or does not 'look' like gold... kinda like ore, or cemented gold? Quite possibly a complete waste of time, but you must admit that it would be a curious experiment, just the same!

The detaching of the plating with nitric acid worked beautifully. How spectacular! I would've been tempted to remove all the foils floating at the surface with a spoon before filtering the solution.

Hey there, just a tip to you because I like watching your methods the most, strenuous as you are toward getting back that gold. You might condense your videos to 10 to 15 minutes, at least SOME of them, as those are the ones you might get back the most traffic. But your analysis stats probably say better.

Your videos are interesting and educational. Have you ever calculated your profit, accounting for the cost of chemicals, raw materials, waste disposal, etc. I know that's not really the goal, but would be interesting to know

The profit in paper dollars: less than zero

If you want an easier way to get the water out of the gold try pouring it on to a paper towel and then you twist the towel to press the water out. Rip off the part where the gold is and then proceed as normal. You can burn the paper towel in the melt dish to get rid of it and pool the gold.

Gold plated fingers and pins will abrade off in a rock tumbler no other media required filter and save the brown powder.

5:43 golden foam on golden bullion

Sree Sree Sree!

That's the only way I do fingers. AP will dissolve gold as well so I stopped doing it a long time ago. Dilute HNO3 works fast. I have done 20 lbs of fingers in a day. I have even melted the foils and Xrayed the buttons, they come it at about 22k on average. So when I get them recoverd I let them sit for a while in fresh Nitric. Give them a few water boils and go to AR. Most cases it comes in at 997 +. Given you don't get paid any more for 999 then you do for 997 . I just sell it to the refiner

woot!

some of those circuit board fingers have copper INSIDE the middle. They might be multi-layered and have copper inside. A long boil in nitric may not be enough to remove it all. I haven't fully watched the video yet, but I can predict the outcome.
