Vedclass · Answer

(D) The extraction of copper from copper pyrites $(CuFeS_2)$ involves roasting in a blast furnace. $CuFeS_2$ is converted into $Cu_2S$ and $FeO$. $FeO$ is then removed as slag by adding silica $(SiO_2)$ to form $FeSiO_3$. The principle behind this process is that at high temperatures,iron has a greater affinity for oxygen than sulfur,allowing it to be selectively oxidized and removed as slag,while copper remains as a sulfide.

Extraction of copper from copper pyrites is done by heating in a blast furnace. On which principle is this method based?
