Copper extractionWikipedia

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (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

copper and nickel ore concentrator

Nickel Ore Mineral Processing Copper nickel can be get from raw ore, then the copper concentrate with low grade nickel and the nickel concentrate with low grade copper can be separate from the mixing concentrate, the nickel concentrate will be sent into the next stopsmelting, nickel matte can be get and then it

Copper Ore Processing Methods

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 direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Copper-nickel ore concentrate shipment Key investment

Construction of a copper-nickel ore concentrate shipment facility . Zapolyarny, Murmansk Region (Kola MMC) The new facility will enable the Company to split its copper-nickel concentrate into low-grade and high-grade. No low-grade concentrate processing will lead to significant cuts in sulphur dioxide emissions in Nickel. By re-arranging

Nickel processingExtraction and

Nickel processingNickel processingExtraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

Copper-Nickel oresDanafloat

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the

Copper Nickel Flotation

Although several investigators have attempted to produce differential copper-nickel concentrates from these ores, their success has been rather , resulting in fairly good copper concentrates (20 pct Cu) but very low-grade (1 to 2 pct) nickel concentrates. Based on this information and the need for separate processing facilities that would be required for each concentrate if separate nickel and copper concentrates


The ore extracted from Raglan Mine is crushed, ground and processed on-site to produce a nickel-copper concentrate, which is then sent to the Sudbury Smelter for further processing. The concentrator treats approximately 1.3 million tonnes of ore yearly, resulting in more than 38,000 tonnes of nickel-in-concentrate annually.

Production activities Production assets The Group

Norilsk Concentrator processes cupriferous and all disseminated ores from the Talnakhskoye and Oktyabrskoye Fields and Copper Plants low grade ores to produce nickel and copper concentrates. The key processing stages include crushing, breaking, gravitation and flotation enrichment, and thickening.
