Watch a gold miner on foxtel who makes kilos of gold bars by recycling the old boat anchor pc computers.

He just carved up the old motherboards burnt them off and recaptured the gold. It was very interesting.

The other waste was a pain for him he just wanted the big old circuit boards.

Now people have laptops, I would say their would be allot less gold in the circuitory board chips comapared to the old boat anchor tower pc's.

What other products contain gold in the circuitory?

We need to work out how many grams of gold in a recycleable object.

How much of a gram in a phone or the old pc's.

I think if you have the technology of a home gold smelter for recycling it may be a good thing.

hi guys , ive been collecting the gold bits from computers for the last 2 years , they are getting harder to find the old ones with the higher gold content . the processors ( the old ceramic types) can have up to half a gram of gold both as plating and as gold wires inside . the newer ones dont have enough to bother with . aqua regia is used to digest the gold plating/ wires . Recycling gold from unusual sources. DSC_2392 i still dont have enough collected to make messing round with the acids worthwhile just yet i estimate i will fet around 8 grams from that lot as it is .

Dont forget about other precious metals.Its amazing how much gets thrown out such as silver kitchenware and jewelery.A friend recently was clearing an old block and dug up two old stainless boilers.Instead of dumping them he though they might be worth something,$1200 later he's a happy man.

The people that were onto it when they had the big boat anchor computers must have laughed.

You have got a pretty good pic their.

i just wish i had collected all those government motherboard computers and then dumped the plastic.

Good job schischer.

I have 2 TCM modules (IBM mainframe CPU units) that have approx 15g of gold in them. I also have 5 cable connectors that were used to connect the mainframe machines under the floor. I think there is around the same amount of gold in them as the TCM. One day I will get around to refining them. I remember a story on he TV a while back where a company was going around and "offering" to take away your old mainframe equipment for free. They were getting around 8 ounces to the ton which was real good returns compared to the 2 or 3 grams per ton in a mine.
