Filo · Accepted Answer

Explanation:A. 2Cu2​O+Cu2​S→6Cu+SO2​(6.40)The solidified copper obtained has blistered appearance due to the evolution of SO2​ and so it is called blister copper.B. Iron is extracted from blast furnace C. The ore is heated in a reverberatory furnace of after mixing with silica. In the furnace, iron oxide slags of as iron silicate and copper is produced in the form of copper matte.D. Hall-Heroult process single is used for the extraction of Al.
