    The process The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate

  • Copper Mining Copper

    Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate can contain between 25 and 57% copper. The concentrate is then processed in a copper smelter. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces.

  • How Extraction of Copper from Copper Pyrites? QS Study

    The copper pyrite is partly converted into sulphides of copper and iron. 2CuFeS 2 + O 2 → Cu 2 S + 2FeS + SO 2. 2FeS + 3O 2 → 2FeO + 2SO 2. The Process in summary: The concentrated ore is heated stoutly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper (II) ions in the chalcopyrite are condensed

    To do this we heat the ore is a furnace with silicon dioxide and air or oxygen. Through this the copper ions are reduced to copper sulphate. The iron is then converted to iron silicate which is removed as a slag. A final blast of air is added to remove the silicate and what you have is pure copper.

  • Silicon dioxide Wikipedia

    Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.
