    Copper Mining and Processing Processing of Copper Ores

    A. Processing of Oxide Ore Oxide ores are generally processed using hydrometallurgy . This process uses aqueous (waterbased) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps heap leaching, solvent extraction, and electrowinning.

    Copper Ore Types Sulfides vs. Oxides Investing News Network

    Copper ore types Oxides. For instance, hydrometallurgical processes are used to treat copper oxide ores that are dominated by soluble minerals, such as copper carbonate minerals. These copper oxide ores are usually leached using sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate solution.

    Leaching Oxide Ores with Sulfuric Acid. Copper is stripped from the steel cathode plates when it is thick enough. This cathode copper is 99.99% pure. Solvent Extraction and Electrowinning (SXEW) production, virtually nonexistent before the 1960s, reached nearly 3.8 million tonnes of copper in 2013.

  • Froth flotation

    Froth flotation

    For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not

    Oxide Flotation Collector Collector for Copper Oxide Ore. Oxflo and Axis show that the more %Mass you recover, the more the %Cu Recovery in increased. Oxflo shows better Gold selectivity obtaining %Au Recoveries in the 20% at around 12% Mass while Axis needs 25% to 50% Mass to obtain around 15% Au Recovery.

    At a blend of 70% sulphide ore and 30% oxide ore, the rougher scavenger copper recovery was as high as 95.5%. The copper recovery from the blended ore using a mixture of collectors was shown to be superior to the recovery obtained using only xanthate after controlled potential sulphidisation. 2008 Elsevier

  • Copper extraction

    Copper extraction

    For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores, both secondary ( supergene ) and primary ( hypogene ), froth flotation is used to physically separate ore
