Acid Mine Drainage Chemistry COTF

Pyrite is one of the most important sulfides found in the waste rock of mines. When exposed to water and oxygen, it can react to form sulfuric acid (H 2 SO 4 ). The following oxidation and reduction reactions express the breakdown of pyrite that leads to acid mine drainage.

Pyrite The Real Story Behind "Fool's Gold"

Pyrite is a widespread natural source of arsenic, which can leach into ground-water aquifers when geologic strata containing pyrite are exposed to the air and water, during coal mining for example. Acid mine drainage and groundwater contamination requires close monitoring to ensure that it has been neutralized before being returned to the earth.

A Review on Novel Techniques for Chalcopyrite Ore

2.1. Mining of Chalcopyrite Chalcopyrite is a common mineral and is found in almost all sulfide deposit and is often disseminated through igneous rock (Haver and Wang, 1971). For lower grade deposit located near the surface, the open pit method is the most practical for the mining of large tonnages of material.

Gold processing Britannica

Endogenetic gold ores include vein and lode deposits of elemental gold in quartzite or mixtures of quartzite and various iron sulfide minerals, particularly pyrite (FeS 2) and pyrrhotite (Fe 1-x S). When present in sulfide ore bodies, the gold, although still elemental in form, is so finely disseminated that concentration by methods such as those applied to alluvial gold is impossible.
