What is the role of silica in extraction of Cu from

What is the role of silica in extraction of Cu from copper pyrite ore? Answer: Silica (SiO2) is used in the processes of smelting of copper pyrite (CuFeS2) ore and in conversion of produced copper matte (refined copper sulfide) into a crude metal as a flux (purifying agent) It reacts with solid impurities, such as iron oxide, and forms a liquid slag with density, smaller than the copper.
