Which of the following statement is correct?
Copper is extracted from copper pyrites. After roasting, the ore is mixed with silica and coke and then smelted in a blast furnace. The matte obtained from the blast furnace is charged into a silica lined converter. Some silica is also added and a hot air blast is thrown into the mixture to obtain blister copper which is purified by electrorefining.
During roasting, copper pyrites are ultimately converted into a mixture of:
Silica is added to roasted copper ores during smelting in order to remove:
Anode mud obtained after electrolytic refining of copper contains:
