This process is hastened by the action of Acidithiobacillus bacteria which oxidize the pyrite to produce ferrous iron and sulfate These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is the form it takes in most mining operations Acid drainage
Pyrite | Earth Sciences Museum | University of Waterloo
Pyrite seldom forms in fresh-water environments The formation of pyrite crystals depends mainly on the iron content of the sediment The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide If there is iron present, iron sulphide crystals begin to grow

The Mining Process The Mining Process 1 Mining – open pit and underground To define the ore from the waste rock, samples are taken and assayed Assay results are used to mark out areas of ore and waste rock, which are mined separately Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers
Acid Mine Drainage, the Unseen Enemy - Valdosta State University During the mining process, a sulfide containing compound can be uncoveredOne of the most common examples is when pyrite (FeS2) is disturbed during the .
The ore consisted of quartz, in which, above the 250-ft level, the iron-minerals were largely oxidized and some free gold was visible; below that level few traces of oxidation occurred, and pyrite constituted the principal mineralizer in the quartz, together with occasional pockets of galena and a few eccentric specks of covellite The 20-stamp mill was equipped with plates for amalgamation .
Pyrite Oxidation Kinetics - How Fast does Pyrite Oxidize
Pyrite oxidation has been studied extensively, in the past, because of its importance in sulfide mineral separations by flotation, in the generation of acid in mine waters and in leaching of pyrite The oxidation of pyrite also plays key role in supergene alteration of ore deposits, the formation of acid sulfate soils, etc Pyrite oxidation is generally recognized as a complicated process .
