Copper mining while copper does occur as a native metal most of the copper used today is mined as ores the ores occur as both sedimentary and igneous rocks and mining methods include traditional underground and open pit mining
Get DetailsThe 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 directsmelting ores are produced the bulk of the copper ore mined is concentrated the milling of copper ores as practiced in the larger
Get DetailsMining 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 metalbearing ore after some or all of a metal such as uranium has been extracted leaching and solvent extractionelectrowinning processes as well as the practice of recycling raffinate at copper mines
Get DetailsOre is taken out of the ground holes are drilled in the ground if its an openpit mine or in the rockface if its an underground mine and explosives are placed in them to blast it open the resulting explosions leave huge quantities of copperbearing rock also known as ore
Get DetailsMining of copper ores is carried out using one of two methods underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels called adits to reach the ore underground mining is however relatively expensive and is generally limited to rich ores el teniente in chile is the worlds largest underground copper mine
Get Details2 days ago until the development of the modern copper mining process it was typically a byproduct of mining for other metals the deposits that contain the largest quantities of copper are called porphyry deposits and the process of extracting it usually involves drilling an open pit into a layer of sedimentary rock how copper forms in the earth
Get DetailsProcess 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 DetailsCopper ore is extracted using two basic methods of mining open pit or underground mining 3 processing of copper ore the first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces this is accomplished by a
Get DetailsMar 21 2019 the copper mountain mine is in the process of expanding to include the new ingerbelle project photo courtesy copper mountain mine canada is one of the worlds major copper producers with the highest concentration of the metal being sourced in ontario and bc most companies mine copper as a coproduct in conjunction with other metals such as molybdenum zinc nickel or lead and
Get DetailsThis compares to 800 million tons of steel and 10 million tons of copper the nickel mining process nickel mining occurs through extractive metallurgy which is a material science that covers various types of ore the washing process concentration and separation chemical processes and the extraction process
Get DetailsCopper mining and processing life cycle of a mine lifecycleofaminepng the life cycle of a mine the stages in the life cycle of a mine are prospecting and exploration development extraction closurereclamation each of the stages may overlap with the next and is very lengthy and expensive
Get DetailsHow does the copper extraction process work most copper is refined from sulphide ores the process includes the following stages the copper ores are mechanically crushed and ground the resulting mixture i s treated using flotation with air injection and agitation to
Get DetailsSince the introduction of hydrometallurgical process for copper in the late 1980s it has been widely used in china especially for copperbearing materials that cannot be effectively recovered by conventional processing methods such as waste rock from openpit ore stripping and lowgrade copper oxide ore hydrometallurgical process is the process of extracting copper from pregnant liquid by leaching
Get DetailsOxide ores and leaching oxide ores and certain sulfide ores are placed onto a leach pad and saturated with weak sulfuric acid solution that dissolves the copper mineral content the resulting copperbearing solution is collected and pumped to a solvent extraction plant
Get DetailsJun 22 2018 however the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective this is why we have broken down the mining process into six comprehensive steps prospectingsurveying the first stage in the mining process calls for skilled workers or ai to apply their geological knowledge in identifying areas where a particular ore can be
Get DetailsIn this process the blister copper is cast into large slabs which are used as anodes in the electrolysis apparatus the anodes are immersed in an electrolyte containing copper sulfate and sulfuric acid pure copper cathodes are arranged between the anodes and a

Get DetailsThe traditional method used at most mines involves the ore being broken and brought to the surface for crushing the ore is then ground finely before the copperbearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material or gangue
Get DetailsThe 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
Get DetailsCopper mines are only set up where there is more than 5kg of copper per tonne of rock 05 by mass ideally the figure should be closer to 2 the flow chart shows you how copper is extracted from its ore and converted into pure metal roll over each stage to get a summary and click to find out more
Get DetailsThe mining of laterites is basically an earthmoving operation with large shovels draglines or frontend loaders extracting the nickelrich strata and discarding large boulders and waste material the ore is loaded into trucks at the face as would be the case in an open pit and hauled to the smelter
