Copper Smelting Chemistry Tutorial

Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed. One of the reactions to remove iron impurities is shown below:

Copper Mining and Extraction: Oxide OresDeze pagina vertalen

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

Treatment of Mixed Sulfide Oxide Ores of CopperDeze pagina vertalen

The oxide orebodies, in which the copper is present about half as sulfide and half as oxidized minerals, and where the recovery to be expected is 25 or 30 lb. per ton of ore, might well be treated first by the method used at New Cornelia, to recover the oxide copper, then reground and sent through the regular flotation operation.

Oxide ores (and certain sulfide ores) are placed onto a leach pad and saturated with weak acid solutions that dissolve the copper mineral content. The resulting copper-bearing solution is collected and pumped to a solvent extraction plant.

Reactions of Cu2S with Cu2O, CuS with Cu2O and CuS with CuO in the molten state were examined in the presence of one atmosphere of argon at 1200°C. A rate law of the form,r SO2 =kNSNO was applicable for each reaction system studied. Comparison of the rate constants for the systems, under conditions of similar initial mole fraction of sulfur to mole fraction of oxygen ratios, showed that Cu2O ...
