iron pyrite production process

Pyrite In The Manufacture Of Iron African Pegmatite

2021-10-6  Nodule counts tend to be greater when sulfur/pyrite grains are added to the molten iron at later stages in the process across a range of iron compositions(6). Up to 0.55% by weight of sulfur as an inoculant is common. Patents to produce automotive-grade cast iron suggest common sulfur contents in the region of 0.2 to 0.3% by weight sulfur(7).

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

2003-3-1  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 is quite complex.
