COPPER Copper production TU Delft

About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

Processing of Nickel Laterite Ores on the Rise

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the ...

Copper extraction Wikipedia

Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature.

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (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 sulfur in the chalcopyrite turns into sulfur dioxide gas.
