Which of the following is an incorrect Match ? (A) Igneous Mineral : Mica (B) Gemstone : Sapphire (C) Ore : Blister copper (D) Alloy : German silver

Extraction of copper is done using 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 blown into the mixture to obtain blister copper, which is purified by electrorefining. The chemical formula of copper pyrites is.
