Pyrite oxidation: a state of the art assessment of the ...

Mar 01, 2003 · The oxidation of pyrite to release ferrous iron and sulfate ions to solution involves the transfer of seven electrons from each sulfur atom in the mineral to an aqueous oxidant. Because only one or, at most, two electrons can be transferred at a time, the overall oxidation process isplex.

Pyrite Oxidation Mechanism by Oxygen in Aqueous Medium

Nov 08, 2015 · Surface. The cleavage of pyrite occurs along the 100 plane Figure 1a direction through FeS bond breaking. As shown in Figure 1b,c, 5 fold iron sites and 3 fold sulfur sites are formed on the surface. All SS bonds remain intact in the ideal cleavage. Figure 1 shows the optimized structure of the pyrite surface.
