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 ...
