  • milling copper sulfide ore feuerwehr-appelhuelsen.de

    Copper processing is a complicated process that begins with mining of the ore (less than 1 copper) and ends with sheets of 99.99 pure copper called cathodes which will ultimately be made into products for everyday use.The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different

  • Copper Mining and Extraction Sulfide Ores

    Some impurities form a slag (such as FeO.SiO 2 ), which floats on the surface of the liquid (like oil on water) and is easily removed. (Courtesy of Xstrata.) The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores.

  • sulfide ore grinding copper

    Copper Ore Crusher,Copper ore grinding mill,Copper ore, Copper ore is mined either at via open pit mines or underground min The beginning for all copper is to mine sulfide and oxide ores through digging or blasting and then crushing In the crushing process, the copper ore is broken into small grain sizes of less than 25 centimeters in diameter by primary crusher

  • Mechanochemical sulfidization of a mixed oxide

    Mechanochemical sulfidization of a mixed sulfide/oxide copper ore by co-grinding with sulfur and additives including Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders was investigated for the first time. Also, the influence of sulfidization during the wet-milling process was examined on the separation efficiency and recovery of copper in detail.

  • What is Sulfide Mining? Mining Action Group

    Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water, environment, and communities.

    2017-4-11 · At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger concentrators has changed to such an extent that comparatively few of the machines in use at the beginning of the period remain in service today.
