I expected a big nugget at the end, but conclusion is a lot of work for not much results haha Gold Recovery Computer Scrap Complete Process Published on Sep 13, 2015 Step by step detailed demonstration on recovering gold from computer scrap circuit card fingers [youtube]http://www.youtube.com/watch?v=2sZUAprS5KI[/youtube]
Wait....... so he spent $39 on 0.7lbs (318g) of scrap material (which works out to a cost of $122.6/kg) This material yields 1g of gold per 500g, so a ratio of 2g/kg. Spot was $1130, so the 2g of gold he could extract per kg is worth $72.66. Which gives a net loss of $50/kg, plus the cost of his time, plus the cost of the consumables he used to extract it. Seems like the only people who make money are the guy who sold him the scrap and the guy who sells him his acids.
