  silica in the extration of copper

  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.

  Silica | Minerals Eduion Coalition

  Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth''s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
