  • Why the Extraction of Copper from Chalcopyrite is so

    About 3/4 th of Copper (Cu) produced in the world has come from Chalcopyrite (CuFeS 2), but it is the lowest standard ore of Copper. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. So, extraction of Copper from it becomes very difficultОнлайн-запрос

  • Copper processing Ores | Britannica

    Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.Онлайн-запрос

  • Extraction Of Copper | Mining, Concentration, Smelting

    Iron in Chalcopyrite is removed as iron silicate slag. Most of the sulphur in Chalcopyrite turns into Sulphur dioxide (SO 2). The reaction of these processes can be written as: \(2CuFeS^{2} + 2SiO^{2} + 4O^{2} → Cu^{2}S + 2FeSiO^{3} + 3SO^{2}\) The copper extracted from this process is mixed with the slag and is called Matte Copper due to itsОнлайн-запрос
