A First Principles Study of the Distribution of Iron in …

to study the distribution of iron impurities in sphalerite (ZnS) at compositions ranging from 3.125 to 12.5 mol% FeS. Our results show that iron is most easily incorporated by direct substitution onto the zinc site and that energies for solution reactions involving FeS are exothermic when the system is zinc deficient. Furthermore, there

Sphalerite

Sphalerite is the most common zinc mineral and the most important zinc ore. When Cd, In, Ga, Ge and Ta are present, they are recovered from sphalerite as well. Zinc is used in protective zinc-coatings on steel, in brass (copper-zinc alloy) production, in batteries and electronics and in the production of white pigment (ZnO - zinc oxide).

Sphalerite

Sphalerite or blende is zinc sulphide and is the main ore of the metal zinc. In Cornwall, sphalerite was found in many mines, often closely associated with lead-bearing minerals. The majority of Cornwall's zinc was recovered from mines whose main product was lead, helping to sustain them when the production of lead alone became unprofitable.
