crushing copper oxide ores for recovering copper

  • Copper Mining and Extraction: Oxide Ores

    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. Scrubbing sulfur dioxide also protects the environment. A by-product of the smelting and converting furnaces is sulfuric acid. In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX

  • Copper extraction Wikipedia

    Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals, the ore is crushed

  • PRETREATMENT OF COPPER ORE PRIOR TO HEAP LEACHING

    research copper ores (copper oxide and copper sulfide ores) were crushed by a jaw crusher and by HPGR and the products evaluated for particle damage, as well as by column leaching to determine the rate and extent of copper recovery.

  • A New Technique for Recovering Copper from Complex

    Eventually, they verified the feasibility of the proposed method for efficient copper oxide recovery and energy saving. The authors observed that the proposed method significantly enhanced copper recovery rate as compared to the conventional traditional methods. For example, by using sodium sulfide and butyl xanthate as a vulcanizing agent and collector respectively, a recovery rate of 32.22%

  • Flotation of Copper oxide ore Fodamon Machinery

    It can improve the recovery of copper oxide ore. The reason is that the decrease of PH value after adding ammonium sulfate is beneficial to the increase of HS concentration, the acceleration of sulfidation reaction and the flotation of copper oxide ore. However, when sulfide and oxidize mixed ores are beneficiated, ammonium sulfate can inhibit sulfide minerals when the amount of ammonium
