what is the process of mining pyrite

Anaerobic pyrite oxidation in a naturally occurring pyrite-rich ...

Pyrite undergoes oxidation when exposed to aqueous oxygen to produce acidic leachate with high concentrations of H+, SO42-, and Fe3+. The oxidation mechanism is currently ascribed to contact between the mineral and aqueous oxygen.

Pyrite - Wikipedia

This process is accelerated by the action of Acidithiobacillus bacteria which oxidize pyrite to first produce ferrous ions ( Fe2+ ), sulfate ions ( SO2− 4 ), and release protons ( H +, or H3O+ ). In a second step, the ferrous ions ( Fe2+ ) are oxidized by O 2 into ferric ions ( Fe3+
