Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation. Also for some copper ore it is combined by both oxide copper ore and sulfide copper ore, after processing test combined processing technologies can also be adopted to extract copper.
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.
Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (% by mass). 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. This is due to the volcanic activity that is part of the process that created the Andes mountain chain.
The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.
The majority of highpressure grinding rolls used in the minerals industry are made by ThyssenKrupp Industrial Solutions. The POLYCOM® operates convincingly all around the world, comminuting copper ore, gold ore, iron ore, diamond ore, platinum ore, coal, granulated blast furnace slag, limestone, cement clinker and other mineral raw materials.
mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions. Depending upon the chemicals used, some minerals
results proved that the application of HPGR devices in given copper ore comminution circuit may improve the effectiveness of downstream grinding process what leads to improvement of the entire circuit work efficiency through decreasing the process ener gy .

Copper extraction refers to the methods used to obtain copper from its 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.
Jun 21, 2019· According to the Coalition for EcoEfficient Comminution, comminution – the process of crushing and grinding ore – is by far the most energy consuming step in the mining process.
This crucial process, which is generally conducted at or very near mine locations to save on transportation costs, involves grinding mined ore to roughly separate copper from waste rock.

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 directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...
Crushing and Grinding You will note that the Oracle Ridge project has utilized a twostage crushing circuit with a double acting jaw crusher and cone crusher. In order to utilize this system, the jaw crusher is oversized to produce all 5 material for the cone mill with a screen in closed circuit. Normally a threestage crushing circuit would have been more conventional, but with the type of ...
Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process .It is a high technological enterprise that integrated research, manufacture, sales and service . The company has multiple subsidiaries such as Mineral ...
In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copperbearing minerals from it.
