Sep 02, 2019 A. Extracting gold from old desk top computers averaged. 5 to 1.03 grams of gold gold has Bennett going up and down but at 1200 per ounce and 32 grams per ounce 31. Something Im using simple math its about 37.00 bucks of gold newer computers are about a 13 of a gram thats the ram, board fingers, processors.
Start by obtaining as many scrap electronics components to reclaim gold from. Generally speaking, older electronics work better because enhanced manufacturing processes use less gold than older electronics, so an old 386 or 486 computer, for example, contains more gold than a modern computer.
Feb 28, 2017 Put ic chips in a stainless steel pot. Add sulfuric acid in a pot until ic chips dip. Sulfuric acid should be 1 inch above from ic chips. Now give a normal flame heat. If you give a strong heat then ic chips will stuck and cant process anymore. After some time, dissolving will start in H2SO4.
Jan 01, 2015 Maximizing simultaneous gold and copper recovery occurred at initial pH 10, pulp density 2 gl, particle size with mesh100 and glycine concentration 0.5 gl, which led to 36.81 gold extraction. The conducted experiment at optimal condition with maximizing gold and minimizing copper as a target caused gold extraction only to 14.02.
wt copper, 0.04 wt gold, 0.15 wt silver, and 0.01 wt palladium. The extraction of these metals from PCBs is both profitable and environmentally worthwhile.
