I need some advice from the experts. A friends cousins uncles brother has about 10k pounds of 5+ year old circuit boards and memory chips/sticks. Is there a feasible way to extract the gold from them? We have some spare gold mining equipment and one of the people involved is swearing you can use the gold mining equipment to crush the boards into a powder and somehow extract the gold with no chemicals. I've researched this a tiny bit in the past and have always seen this done with chemicals which we don't want to get into. Could we possibly use a stong electromagnet to get the gold from the powder? Also what would we do with the powder when were done? Would this be toxic waste and need to pay to be removed. I know this doesn't exactly fit the topics on this forum but I have faith there are some really smart people here who will know about this. Thanks for any help you can give.
