    use of SiO2 in the extraction of copper from copper matte

    6 years ago. 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 matte
