Roasting

Vedclass · Answer

(B) Roasting is the process in which the ore is strongly heated in the presence of excess air.In the extraction of copper,after crushing and concentration of the ore,it is heated in a reverberatory furnace.Copper pyrites $(CuFeS_2)$ is partially oxidized,and a part of the sulfur in the ore is removed as sulfur dioxide $(SO_2)$.The given equation $2CuFeS_2 + O_2 \rightarrow Cu_2S + 2FeS + SO_2$ represents the partial roasting of copper pyrites.

$2CuFeS_2 + O_2 \rightarrow Cu_2S + 2FeS + SO_2$
Which process of metallurgy of copper is represented by the above equation?
