I dont know why you werent recommened thru You Tube earlier. I live my life outside of work and family refining. Im happy to share my recovery rates with you. I dont know where you are located but I do know of one company listing on Ebay that I buy from regularly. You are right about the fiberglass bit holding onto a portion of the gold. Ive backed this up with a microscope. I use a 2000 micron mesh when dealing with the Bgas to fully seperate the fiberglass vs the rest

I'm located in the UK. I've thought about buying a few high micron screens and testing to see at what size does the gold no longer fit through and if I can remove more material without compromising the gold yield

@3-2preciousmetalrecycling I've tried as high as a 1500 micron mesh... I lost gold within the fiberglass. The 2000 works best for me. Rather than loosing 50 percent for using higher mesh vs lower. I loose 10% that I build up to refine in larger batches.

I’m with you Electronnicscrapper, why didn’t the algorithm recommend sooner? Subscribed also, thanks for the video 3-2.

Also quick tip, get rid of the plastic bag and magnet, too much faffing, build a small electromagnet, all you need is a pc power supply, a magnetic steel/iron nail, a switch, and a decent length of thin enamelled copper wire and some electrical tape. Loads of videos on YT about making these. You can use a battery but they got hot after a while, hope it helps and keep them vids coming.

you need to burn the chips a second time to white ash, otherwise there will be losses. if you leave black ash, it will absorb gold. P.S. hello from Ukraine.

I use a electric rotisserie for BBQs'. It has a cage that shuts. I lined the cage with fine steel mesh like window screen. It holds a kilo + of ICs'. I built a fire brick box to put the cage in. It has a hole in the side for the burner. I set all that in a steel pan. Turn on the rotisserie and light the burner. As they burn they tumble , and the ash falls into the tray. Most of the legs and the silicon stays in the basket. Leaving very clean ash with the gold wires. You get the idea.

That's an absolutely brilliant idea, I really like that. I had thought of something similar but a bit bigger for de-populating boards. Boards heat up solder melts, and components fall out onto a tray. I keep thinking of building it, never get round to it. I'd never even thought of an automatic chip crusher. Thanks for watching 👍👍

I don't for gold recovery. I like to recover the gold first, and then once I have a decent amount, I'll refine it to get it pure. When I do the refine, I use sulfamic acid to remove any lead as I can not buy sulfuric acid in my country

@3-2preciousmetalrecycling20 күн бұрын
I do it when I refine all my gold after recovering just as a precaution it is possible to pick up small bits of lead, tin, copper and silver from the boards the bgas come off or the containers I store them in while I build up a batch or just from not separating the material properly. I also use ammonia to wash my gold when refining as a precaution just in case there is any silver chloride present. It cleans the gold up beautifully

Why you dont use urea or sulfamic acid to neutralize solution before drop?
@3-2preciousmetalrecycling19 күн бұрын
I don't overuse nitric acid. I use enough pottassium nitrate, or sometimes nitric acid, to get the job done. Once a reaction has finished, I add a little more. If I don't get any reaction, it means all the gold is dissolved. Therefore, there is no need to use urea. Some people use urea to remove excess nitric, but because I don't have an excess, there is no need to. Thanks for watching 👍

If you put the chips in AP it will dissolve the legs , then crush and burn , burn again , it works well in my opinion to make. if your up for a friendly challenge I have a video in response , it’s from CPU scrap and pins ( >1.5 g)

That sounds good. Just took a quick look at your channel and subscribed. I like the look of that copper cell. I had thought of doing something like this for non-ferrous pins. I'll be watching a few more of your videos in the morning 👍👍
