Pyrite vs Gold – how to spot the difference

2018-8-5 · The first difference between pyrite and gold is the fact that pyrite isn’t even a metal, it’s a mineral. PYRITE — “a very common brass-yellow mineral, iron disulfide, FeS2, with a metallic luster”. GOLD — “a precious yellow metallic element, highly malleable and ductile, and not subject to oxidation or corrosion. Symbol: Au”.

In galvanic cell arrangements gold is electrochemically deposited on semiconducting sulfide minerals (pyrite, arsenopyrite, chalcopyrite) from aerated as well as H2S-saturated, gold-bearing 1 M KCl solutions. Observed cell potential differences of about 0.4–0.6 V in setups with one sulfide in aerated (cathode) and the other in H2S-saturated (anode) solutions are comparable with

The best answer as to how to recover that gold depends on the amount of pyrite you intend to process. If you have only a few pounds, it can be roasted by heat in the open air and then mixed with a flux like sodium borate and melted with a collector metal like copper. The melt can be poured into a mold and the gold will now be alloyed in the copper.
