The presence of pyrite (FeS2) in coal can cause or contribute to several problems for the coal mining industry. These problems, which include spontaneous combustion, roof falls, floor heave, and accidental explosions in coal surface mining when ammonium nitrate-fuel oil (ANFO) explosives are used, result from pyrite oxidation. Pyrite oxidizes exothermically in the presence of air and moisture to f

One is manifested as cleat pyrite (Birk, 1990, Birk et al., 1986, Casagrande, 1987) that occurs as submillimetre-thick “sheets” in coal joints, cross-cutting coal-bedding planes, and the second conformable to bedding planes.The latter is very fine-grained pyrite, however, deposited as discontinuous stringers

Pyrite Oxidation Drives Exceptionally High Weathering

The sulfate exports from pyrite oxidation in mountaintop‐mined catchments account for ~5–7% of global sulfate derived from pyrite, despite occupying less than 0.006% of total land area. Further, the suite of weathering reactions liberate 100–450 kg of rock‐derived C·ha −1 ·year −1 as CO 2,with an additional 90–150 kg C·ha

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.
