Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Influence of grinding on flotation of copper sulphide ores is investigated by tests in laboratory. • Milling procedure affects concentrations of Cu and Fe in the pulp and flotation results. • The effect of grinding condition on the flotation result is ore-dependent. •

Copper Sulfide Ore About 80% of the world's copper-from-ore originates in Cu-Fe-S ores, such as chalcopyrite (CuFeS2) and chalcocite (Cu2S). The concentration of these minerals in an ore body is low.

The polymetallic sulfide ore of copper, lead, and zinc is widely found all over the world and is often associated with rare metals such as gold and silver. The economic value of the comprehensive recycling of this of ore is large[1].

Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter.

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".

Copper Ore Grinding. Porphyry copper ores usually are medium to medium hard and require grinding to about 65 mesh to economically liberate the copper minerals from the siliceous gangue. Sometimes a regrinding circuit is advantageous on the rougher concentrate and on the scavenger concentrate.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.

Most copper facilities use a combination of rod and ball mills to grind sulfide ore (Figures 1-6a and b). Rod mills use free steel rods in the rotating drum to grind the ore. A ball mill works by tumbling the ore against free steel balls and the lining of the mill.

Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 - 8 inches. This material is then fed to a secondary grinder that further reduces the size to about 1 - 2 inches. The next step is to feed the crushed ore into a wet grinding process in tumbling mills.

The oxidised sulphide ore was studied by artificially oxidising a copper sulphide ore to various states during 16 months. For each oxidation state, the effect of chemistry was studied through a series of grinding and flotation tests completed under various grinding environments.

Mined sulfide ores contain pentlandite, pyrrhotite, chalcopyrite and gangue rock. A high-grade nickel concentrate is produced from these ores by the following minerals-processing techniques: (a) crushing and grinding the ores to liberate the nickel- and cobalt …

sulfide ore grinding copper - sulfide ore grinding copper [ ... Our ball mill machine can be used for many mineral grinding,such as gold ore,copper ore,iron ore and zinc ore …

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.

Misreported pyrite into copper concentrates dramatically declines copper grade and its recovery. In this study, the effect of sodium sulfide, sodium metabisulfite (SMBS), and their dosages (100, 200, 300, and 400 g/t) were investigated on chalcopyrite and pyrite floatabilities in a high pyritic copper sulfide ore.

Aug 14, 2015· copper extraction from sulphide ores by chloride offers 63 lead sulphide products. About 17% of these are sulfide, 17% are mineral separator, and …

Extract maximum value with minimum environmental impact when processing sulfide copper ores. We understand the intricate challenges and have the expertise and experience to design and optimize solutions to suit your specific ore type and – from complete concentrator plants to specific equipment.

iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in …

Copper sulfides describe a family of chemical compounds and minerals with the formula CuS y. Both minerals and synthetic materials comprise these compounds. Some copper sulfides are economically important ores. Prominent copper sulfide minerals include Cu 2 S and CuS .

Proponents of sulfide-ore copper mining argue that the choice between this new type of mining and amenity-based development is a false choice for the Arrowhead region (Praxis Strategy Group, 2017). Those making this claim point to the continued existence of the taconite mining industry during the

Copper Ore Processing Methods 911 Metallurgist Apr 11, 2017 The milling of copper ores as practiced in the larger concentrators has field the development of pebble-mill grinding, the substitution of balls for pebbles, the gravity method in the treatment of low-grade sulfide copper or

Copper, uranium, vanadium and other metals are produced by solvent extraction. The figure below is a simplified schematic of a typical copper solvent extraction process. Oxide copper ore, low-grade copper sulfide overburden, and other copper-containing materials are stacked into a heap.

For sulfide ores, on the other hand, selective flotation normally follows the crushing and grinding stage and requires an optimal degree of liberation. In the flotation process, the finely ground ore, mixed with water and special reagents, is agitated by mechanical and pneumatic devices.
