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

Copper and its alloys are also widely used in plumbing components, building construction as well as industrial machinery and equipment. An average car contains more than 20 kg of copper and suburban homes have around 200 kg of copper. The main ore mineral of copper in Australia (and worldwide) is chalcopyrite (CuFeS 2).
Polysius in Australia Grinding rolls for gold Polysius USA. In southwestern Australia the country''''s biggest gold mine is being readied for highpressure grinding rolls to Australia to process the gold and copper ore. Read More
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 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.
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 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.. As in all mining operations, the ore must usually be beneficiated (concentrated).

grinding process in copper production. at britannia the copper ore contained just over 1% copper (though in the early years it was grinding rod mills (large cylinders similar to cement mixer) base metals (non precious) are separated by flotation during the mining process.
This process was invented in the 19th century in Australia. It was used to recover a sphalerite concentrate from tailings, produced using gravity concentration. Further improvements have come from Australia in the form of the Jameson Cell, developed at the University of Newcastle, Australia.

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. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60% copper.
