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 KZitem 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).

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.

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.

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.

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.

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

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!

Hey bud, just wondering if your camera equipment takes a bit of a hit from the gasses off all the chemicals you use?

Ok i have a question im about to start to refine some gold from electronic scrap anyway wat iblike to know is doing the electrolisis method deos the liquid have to be gold cloride or can i use a vinegar salt solution

Electrolytic is a refining process. Using salt and vinegar to strip gold off of scrap is a recovery process. Recovery and refining are two totally different processes.

I don't understand. Why detach and filter out the foils if it's all going back in the beaker with the stripped fiberglass for the AR step? Could AR just be the first step?

I could, but it’s best to remove base metals that are under the gold foils with the nitric boil first. Then get rid of the liquid that contains the base metals. Some of the valuable material came over as I poured the liquid off into the filter. That’s why, after all the blue liquid was poured off, I added the filter back into the beaker with the clean fiber board fingers and loose gold foils - the filter had a few gold foils, not much, but enough to add to the recovery. These fingers produce very small yields. So my thinking was to include the filtered tidbits because in refining, every little bit counts. Having said all that; as soon as I dropped that filter back into the beaker I realized that I should have put it into a separate beaker, added AR to dissolve the gold (in a separate beaker). Then added the gold solution from that separate beaker in with the gold foils that I dissolved in the large beaker with the fiber boards. Adding the filter back to the big beaker was a mistake. Finally, this took me ten minutes to compose and write out this explanation. And that’s why I don’t offer any tutoring or training services. It takes too long!

Please see my video titled “trimmed fingers in aqua regia.” Then you’ll understand why it’s important to remove the base metals first before going to aqua regia.

Nice. I wonder how that compares to just incinerating the boards and processing the ash?

I was curious about just incinerating the boards too. Isn't the first step of most refining incineration?

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.
