In gold mining, two main processes, one based on mercury and the other based on cyanide, are used to aggregate gold dust after its segregation from the placer deposit or from the ore‐bearing rock. These processes are very toxic to the artisanal community and to the environment, in particular, to rivers where all the chemical waste is dumped ...

Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral. In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent.
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction..
