Oxidation of pyrite during extraction of carbonate

A wealth of literature exists on the oxidation of pyrite by Fe 3+ and we believe this mechanism drives the oxidation of pyrite during CAS extraction, during which the oxygen used to form sulfate is taken from H 2 O, not O 2. Consequently, extracting CAS under anaerobic conditions would only slow, but not halt, the oxidation of pyrite.
