Pyrite Concentrate – Eti Bakır

Pyrite Concentrate. Depending on the procedures employed in processing the chalcopyrite copper ore found in the Eti Bakir Kure mines, first the pyrite-copper minerals are separated. While the copper minerals, separated in this phase, constitute the copper concentrate, pyrite minerals constitute the pyrite concentrate.

Efficiently Produce Iron Concentrate from High-Purity Pyrite

The study attempts to produce iron concentrate from a high-purity pyrite concentrate using oxidizing roasting at industry scale. The effect of key parameters, i.e., roasting temperature, excess air coefficient and roasting intensity on the Fe and S content in the pyrite cinder was fully investigated. The results indicate that the roasting temperature plays a key role in decrease the S content ...
