Copper production figures can change rapidly, but in the 2018 financial year, Escondida’s total production reached 1,213 kilotonnes. The mine has processed more than 2 billion tonnes of ore
Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.
The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off
Question. Suppose that you are building a new house. It will take about 90 kg (198 pounds) of copper to do the electrical wiring. In order to get the copper in the first place, someone needs to mine solid rock that contains copper, extract the copper minerals, throw away the waste rock, and smelt the copper minerals to produce copper metal.
Commercial copper ore deposits today contain from 0.5 to 6 percent copper, or between 100 and 1000 times the crustal average. In contrast, iron and aluminum constitute around 5.8 percent and 8 percent of the earth’s crust, respectively, and their commercial deposits need to be only 3 to 10 times as concentrated as the crustal aver-age.
From the start, the Bingham Canyon Mine was one of the leading copper-producing mines in the world, and returned a good profit mining ore with less than two percent copper. Mining by open-pit model using large-scale mechanization was copied by other US mines, in Ely, Nevada (1908), Santa Rita, New Mexico (1910), and Ajo, Arizona (1917). The

Copper Ore Grade, Mining, and Tailings: Ideas for Class Discussion. Copper occurs in Earth's crust (average) as 0.0058% by weight. A typical ore body has a grade of copper of 1-4% by weight. The concentration factor of copper in an economically viable ore body is about >80-100 times that of the average value of copper in the Earth's crust.
There is a broad range of TENORM concentrations in copper mining wastes. Mining and extraction of copper by surface or underground methods can concentrate and expose radionuclides in the waste rock and tailings tailingsThe remaining portion of a metal-bearing ore after some or all of a metal, such as uranium, has been extracted.. Leaching and
These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral.
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and
