Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide silica, calcium carbonate CaCO 3 and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.
Copper is extracted from its principal ore Copper pyrites CuFeS 2. The ore is concentrated by froth flotation process. Then, the concentrated ore is roasted in a furnace where reactions remove sulphur and Arsenic gases SO 2 SO 2 and 4As3O 2 2As 2 O 3 The copper pyrite gets converted to a mixture of Cu 2 S and FeS by the reactions given ...
the copper in a co,per deposit must be between a hundred and a thousand times more concentrated than the crustal average, whereas iron and aluminum need to be only three to ten times as concentrated. Thus, copper is indeed a localized zone in the earths crust that contains copper-bearing minerals in unusual quantities. 8.
Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts. The copper has concentrated almost entirely into the sulfide fraction, and if this becomes separated from the siliceous melt it can become deposited in veins or in fissures in the host rock by hydrothermal or other geological ...
