Oxide mineralisation occurs mainly as chrysocolla with minor brochantite native copper and copper-iron-manganese oxides and hydroxidesThe projectâ€™s previous shareholder xstrata copper announced a 28 increase in the total estimated mineral resource at the mine in 2008 representing the equivalent of an additional 11 million tonnes of.
The dried copper concentrates are sent to the smelting operation where it is reduced and melted in several operationsAt the end of this smelting process the copper is about 99 pureThe copper-bearing solution is collected and pumped to the extraction plant where it is purified.

The escondida mine is the largest copper mine in the world and is located in the atacama desert in chileMining operations include both sulfide and oxide ore heap leach operations.
The mine was placed on 'care and maintenance' in february 1958 after producing about 3500 tonnes of cop per from sulphide concentrates and direct-smelted high-grade oxides anonymous 1978Work was not resumed until 1969 when plans were formed for opencast production to begin in 1973 at the rate of about 16 000 tonnes of copper per annum.

There are two distinct types of copper deposits: sulfide ore and oxide oreCurrently the most common source of copper ore is the sulfide ore mineral chalcopyrite which accounts for about 50.
There are two distinct types of copper ore the sulfide ore and the oxide oreThe sulfide ores are beneficiated in flotation cells while the oxide ores are generally leachedFirst the copper ore from a open pit mine is blasted loaded and transported to the primary crushersThen the ore is crushed and screened with the fine sulfide ore.
There are two main types of copper ore: oxide and sulfideCopper oxide is more abundant closer to the earth's surface but is typically a lower-grade ore due to less concentration.
There are two types of copper ore sulphide ore and oxide ore and each is treated differently in order to liberate the copper insideSulphide ore â€ treatment processThe copper is liberated from the sulphide ore through a chemical processes called flotationThe resulting copper mixture is called concentrate which is a grey-black.
These may be mined copper minerals that are in oxidized form - minerals such as azurite 2cuco 3 cuoh3 brochantite cuso 4 chrysocolla cusio 3 2h 2 o and cuprite cu2o residual copper in old mine waste dumps whose sulfide minerals have been oxidized by exposure to the air or sulfididic copper minerals that have been oxidized by.
These oxidised copper minerals are found in weathered regions of most copper sulphide ore bodies the overlaying oxidic ore is usually stockpiled after it is removed from the sulphide lode and left.
This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide oresScrubbing sulfur dioxide also protects the environmentFor example: feos sio 2 sâ†’ feoSio 2 slag this is very similar to the removal of impurities in the blast furnaceThe liquid left is a mixture of copper sulfides and iron sulfides.
Well-developed copper oxide zones appear to form through two distinct mechanisms: 1 via substantial copper addition to a volume being oxidized including the formation of exotic copper deposits and 2 through in situ oxidation of a copper-bearing sulfide resource.
