others, 1996, 1998). Upon mining, however, pyrite in the deep-lying, unweathered strata is exposed to oxygenated air and water within underground workings or surface mine spoil. The spoil com-monly consists of a heterogeneous mixture of rocks that are inverted stratigraphically relative to their original positions (Cravotta and others, 1994).

What is Pyrite. Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Kinetics of Pyrite Oxidation The acidity of coal-mine drainage is caused primarily by the oxidation of the mineral pyrite (FeS 2), which is found in coal, coal overburden, and mine waste piles.Pyrite oxidation and the consequent generation of sulfuric acid have long been recognized as major contributors to acid rock drainage, yet pyrite reactivity remains poorly understood.

Acid Mine Drainage - an overview | ScienceDirect Topics

A form of underground coal mining where a longwall (typically about 250–400 m long) of coal is mined in a single slice (typically 1–2 m thick). The longwall “panel” (the block of coal that is being mined) is typically 3–4 km long and 250–400 m wide. Overburden. In mining, overburden is the material that lies above the area to be mined.
