how is copper ore separated from the host rock

br> Copper Mining and Extraction Sulfide Ores. Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. Ideally, the figure should be closer to 2%. The world's largest copper ore deposits are found in Chile on the west coast of South America.

The Copper AgeThe Bronze AgeThe Middle Ages and LaterMiningAlso in This IssueIf sulfide ores containing iron and copper are to be smelted, an understanding of both the iron and the copper systems is needed. Again, as in Figure 2.1.3 for the Cu–S–O system, the calculations are limited to oxidation by industrial oxygen so that the pressure of SO 2 will be about 1 atm., except where oxygen pressure is appreciable near .

In cases where the next step is leaching (most frequently in the case of oxide ores), complete liberation of the copper minerals is not always necessary; the ore needs to be crushed and ground only to the extent required to expose the surface of…

Gangue | geology | Britannica

Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.Copper is also used in construction.

Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.

separation, cooling across a temperature gradient, pressure decrease, fluid mixing and reaction with host rocks. A large variety of geological processes can meet the essential requirements for ore deposit formation and the concentration of ore elements is best viewed as part of the geological (and geochemical) cycle.

ORE DEPOSIT TYPES AND THEIR PRIMARY

Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e.g., PGE alloys, arsenides, bismuthinides). The oxide ore bodies include stratiform, podiform, and breccia-related chromite .

Ore Depositan overview | ScienceDirect Topics

Copper deposits occur in sedimentary and volcanogenic rocks within a wide variety of geologic environments where there may be little or no evidence of hydrothermal alteration. Some deposits may be hypogene and have a deep-seated source for the ore fluids, but because of rapid cooling and dilution during syngenetic deposition on the ocean floor, the resulting deposits are not associated with .

Copper Deposits in Sedimentary and Volcanogenic Rocks

 · Physical separation usually involves the difference in mass between gold and most of the other associated minerals. Once the gold is physically separated from the host material and of a relatively similar size it can be separated using a rotary bo.

used to extract gold from low-grade ore deposits; crushed ore is placed on pads that have bottoms of asphalt or impervious plastic sheets, a solution of dilute cyanide is sprayed on the ore, the cyanide percolates down through the ore for several weeks to months and leeches out the gold, now a solution, the gold drains off the pad, the gold is pumped to a recovery plant where the gold is .

 · Porphyry-type ore deposits are among the world’s premier metal resources, supplying most of the copper, molybdenum, and a substantial part of gold production ().They form in response to focused expulsion of metal-bearing saline fluids from large chambers of cooling hydrous magma ().A restricted zone of ore-mineral precipitation within a more extensive plume of fluid up-flow is thought to …

Porphyry-Copper Ore Shells Form at Stable Pressure

However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to be separated. 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 .

Copper ore is predominantly in the form of copper-iron sulphides so an enduring problem has been how to simultaneously create enrichments in both copper and sulphur. Volcanoes rich in copper tend .

The formation of the porphyry copper deposit at El Salvador culminated volcanic activity in the Indio Muerto district. Host rocks for the ore are Cretaceous andesitic flows and sedimentary rocks overlain unconformably by lower Tertiary volcanics. Early rhyolite domes, formed about 50 m.y. ago and roughly contemporaneous with voluminous .
