Pyrite is a common symbiotic and associated metal sulfide mineral found in coal mines and other metal mines. In the presence of air, water, or microorganisms (such as Thiobacillus ferrooxidans), pyrite can undergo complex water–rock reactions such as leaching, oxidation, and hydrolysis, resulting in the formation of acid mine drainage (AMD). AMD is a kind of mine wastewater with …

pyrite uses in coal mills

Before use, the pyrite was crushed in an agate mill and sieved to less than 38 μm in order to obtain a suitable size fraction. The starting material was subsequently cleaned using a 0.1 M HCl solution to remove iron hydroxide and/or iron oxy-hydroxide patches from the surface and stored under vacuum in an anaerobic glove bag.
