Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and …

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. This is used to make sulphuric acid via the Contact Process. Much like in the Blast Furnace, the calcium carbonate is involved in the production of the slag.

Chalcopyrite is a copper iron sulfide mineral, meaning it is composed of sulfide, disulfide, iron, and copper. The chalcopyrite mineral is also higher in copper ore content than any other mineral. It has a tetragonal crystal system, a Mohs scale hardness of 3.5, and it generally has a gold-to-brass color.

DetailsCoal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.

Prior to melting, chalcopyrite is in a strong lattice formation, and is difficult to dissociate. As temperature increases, bond energy decreases, so the decomposition of chalcopyrite requires relatively lower potentials, but efforts for molten-state processing have been hindered by the persistence of high electronic conductivity of chalcopyrite.
