Chalcopyrite an overview ScienceDirect Topics

The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing 50% copper.In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the CuFeSO system at 1 atm SO 2 as a function of temperature (Rosenqvist 1978).Unlike the system for lead, the copper and Cu 2 S melts are nearly immiscible

Chalcopyrite

On exposure to air, chalcopyrite oxidises to a variety of oxides, hydroxides and sulfates. Associated copper minerals include the sulfides bornite (Cu 5 FeS 4 ), chalcocite (Cu 2 S), covellite (CuS), digenite (Cu 9 S 5 ); carbonates such as malachite and azurite, and rarely oxides such as cuprite (Cu 2

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas.
