Hydrogeologic and environmental impact of amjhore
The Amjhore pyrite mine is located in the north- east of Peninsular India (Fig. 1), and the pyrite ore is sandwiched within the Vijaygarh shales in Vindhyan system However, pyrite is still mined for sulphur to a limited extent in China, Russia and India. Most pyrite is now mined for its contained gold. These deposits are huge and low grade; the (sub) microscopic gold Full article: Pyrite the firestone Taylor & Francis

The analysis reveals that pH of the mine water (AMD) samples collected in the non-monsoon season is higher than those collected in the monsoon season because of the low rate of pyrite oxidation in the winter due to low temperature (Sgambat et al., 1980; Baruah et al., 2016) where pH is a major contributing factor for pyrite formation (Ryan In this study, a total of 119 soil samples were taken around the 35 waste rock heaps which are scattered in 12 mining sites in an abandoned pyrite mining area (Baihe County, Northwest China).(PDF) Characterization and risk assessment of soil

Pyrite mining. For centuries pyrite was the main source of sulphur until it was displaced by Frasch sulphur from the evaporitic caprocks of saltdomes, and more recently by scrubbed sulphur captured in the It is formed by a series of complex geo-chemical and microbial reactions that occur when water comes in contact with pyrite in metal-ore/coal in presence of oxygen.

Water Free Full-Text Review: Acid Mine Drainage (AMD) in
Source. Based on the research results of AMD in abandoned coal mines in Shanxi, the exposed pyrite in the coal seams is the main cause. When pyrite reacts with oxygen and water, the products are Fe ions and sulfuric acid. The specific reaction equations are as follows: 2FeS 2 + 2H 2 O + 7O 2 → 2Fe 2+ + 4 SO 42− + 4H +.In the present study, the potential use of the industrial waste residues, such as coal fly ash and clinker dust, was evaluated in inhibiting acid mine drainage generation from pyrite-rich wastes using non-saturated column experiments. Two columns (B and C) were filled with a mixture of industrial residues over pyrite-quartz sand (PS), Inhibition of Acid Mine Drainage from a Pyrite-rich Mining

In the present case, chemical pollution is caused by exposing pyrite minerals to oxidation or leaching, resulting in undesirable concentrations of dissolved materials.
