First a slow chemical process with O 2 as electron acceptor will initiate the oxidation of pyrite: FeS 2 + 7 2 O 2 + H 2 O → Fe 2+ + 2 SO2− 4 + 2 H + This reaction acidifies the environment and the Fe 2+ will be formed is rather stable. In such an environment Acidithiobacillus ferrooxidans will be able to grow rapidly.

Feb 09, 2017Gold concentrates tend to be mostly iron, so they are also known as "black sands.". Gold concentrates are also made by grinding down ore, quartz, or other productive rock types into sand. This procedure is much faster and easier than panning, but the tradeoff is a final product that has less gold "concentrated" within.
