Pyrite Oxidation Kinetics - How Fast does Pyrite Oxidize

Feb 19, 2018  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 which includes several oxidation/reduction reactions, complexation and hydrolysis reactions, and solid/solution equilibria.

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.
