Pyrite Oxidation Kinetics - How Fast does Pyrite Oxidize

The product layer consists of iron compounds (hydroxides, oxides, etc.). This layer may be uniform or non-uniform, porous or non-porous, adherent or non-adherent, depending upon conditions of oxidation. The nature of the product layer is likely to play a key role in the flotation and depressant behavior of pyrite.
