Poor copper concentrate grade when processing high proportions of supplementary, West Dome, ore due to lower liberation of copper sulfi des as compared to the primary ore source, Main Dome. Copper regrind A copper regrind mill and preclassifi cation circuit for the regrinding of copper rougher concentrate (ISAMill M3000 MW)
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 first grinding in the mill reduces the ore to pieces 6 in. in diameter, after which it is transferred by truck to a primary grinder. At the end of the process it enters the concentrate plant where it is reduced in size in a grinder comprised of bar mills and ball mills.
These concentrates are mainly destined for export markets most copper produced in Peru is shipped to China, followed by Japan, South Korea and Germany, among others. Copper output in Peru grew
Copper concentrate is smelted and converted to metallic copper, which allows it to attain forms that can be submitted to further refining, more than 99% pure, as in copper anode and copper blister. The main application of copper anode is to use it as raw material in the process of electrolytic refining, to produce the electrolytic refined cathode, purity %.
ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.

#0183;#32;In 2009, approximately of zinc ore was processed at Antamina, an increase of 10% over the previous year. Approximately 35Mt of ore and 370Kt of concentrate copper were produced during the same year. Production of zinc metal in concentrate was 154,000t, an increase of 31% over 2008. About of ore was processed in 2010.

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copperinconcentrate (usually 2729% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena.
Reasons for Copper Ore Sorting cont. Preconcentrate feed into highgrade and lowgrade stockpiles: Optimize multiple process streams send ore to either mill, heap leach or smelter. Allows smaller mills to be built or increase capacity of an existing mill. Manage ore
This the processing plant at one of Chiles largest copper mines, El Teniente. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. (Courtesy of Rio Tinto.) After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate.
#0183;#32;The world''s 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the world''s total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The makes the cut, as well, with two mines among the top 20. Copper is expensive to mine and refine.
#0183;#32;The initial plan was to increase the mines annual production to 70Mt, a sevenfold increase if the expansion proceeds. Copper production would have grown from approximately 180,000tpa to approximately 750,000tpa. This would include 500,000oz of gold, 500,000t of copper and 15,000t of yellowcake. Existing average gold production is 80,000oz pa.

Copper ore concentrate processing. Because the metal concentration is usually quite low in nonferrous ores, the first stage in mineral production at the mine is ore beneficiation, usually consisting of the processes of milling (crushing and grinding) and concentrating (usually consisting of a series of steps including flotation and dewatering by thickening and filtering).
