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
The ore processing plant is also called beneficiation plant. It is a kind of production line for selecting many kinds of mineral ores. Ore processing plant mainly has two processes: the flotation separating process and the magnetic separation process.
COPPER Copper production. Copper production About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1.

And thirdly, there was an urgent need for acid to treat oxide copper ore in our processing plant." The smelter was brought to full production in an unprecedented five months . The year was 2011.
Copper Alliance members surveyed demonstrate continued positive progress in the amount of water they are able to recycle and reuse during copper production. For an example of the steps companies are taking to reduce the amount of freshwater they consume, take a look at the new desalinization plant at BHP's Escondida mine.
Copper sulphate is used to kill algal blooms in water reservoirs, to protect timber, to stop plant roots from blocking rains and sewerage systems and to kill insects. Fertilisers. Copper production was boosted in the 1950s and 1960s by the need for copperbased fertilisers to aid crop growth in previously unproductive land. Bronze
