Copper Mining and Processing: Processing of Copper Ores

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 …

    Copper Ore Processing Methods

    Copper Ore Processing Methods The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.

    Copper extraction Wikipedia

    Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically grade between 37% and 40% copper-in-concentrate…

    How copper is made material used processing steps

    The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased. Some of these steps are conducted at the mine site itself, while others may be conducted at separate facilities.

    Copper Mining and Extraction: Sulfide Ores

    The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate.

    The copper is concentrated further by slurrying the ground ore with water and chemical reagents. In this process, air is blown through the mixture, and the copper floats to the top. The copper is then removed with a skimmer. At the end of this step, copper concentrations are typically between 24 and 40 percent.

    Copper Flotation Mineral Processing Metallurgy

    The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.

    Copper Mining and Production Processes Explained

    Concentrating. The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting. This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine.
