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. 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 Get price

How and When to Perform a Copper Sulfate Test —

2017/8/4The MIL-STD-753 copper sulfate test provides the process for a 1.6% dilution by weight solution. Although this is an acceptable testing method, in some cases it is necessary to perform a comparative test by mixing a 3% and 5% dilution by weight solution.Get price

Mining and Extraction: Oxide Ores

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.Get price

Extraction of Crude Metal from Concentrated Ore

2020/4/1The process of extraction of metals by dissolving the ore in a suitable chemical reagent and the precipitation of the metal by more electropositive metal is called hydrometallurgy. For example: Concentrated argentite, Ag 2 S is first treated with a dilute solution of NaCN to form the soluble complex, sodium dicyanoargentate (I).Get price

Copper Mining and Extraction Sulfide Ores

Copper minerals and ore are found throughout the Earth's crust. They occur in both sedimentary and igneous rocks. The outer 10 km of the crust contains 33 g of copper for every tonne of rock. This is not enough to make it commercially viable to extract the rock.Get price

Copper extraction

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 Get price

How copper is made

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.Get price

The Extraction of Copper

The Process The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage).Get price

Copper production: Zambia vs. the DRC

Most copper mines in the DRC are estimated to have an average ore grade of over three percent, far higher than the global average of between 0.6% and 0.8%. For example, the Tenke Fungurume copper mine – the biggest mine in the DRC in 2016 – has an average ore grade of 2.6% as compared to a global average of 0.8%.Get price

Copper production environmental impact

• Depending on whether an ore is sulfide or oxide, the process follows one of two routes. Beneficiation • Beneficiation is the concentration of ore through separation into desirable mineral-the part of the ore that is useable; and gangue (pronounced 'gang') – the part of the ore that is commercially worthless.Get price
