The reaction of these processes can be written as 2CuFeS2 2SiO2 4O2 → Cu2S 2FeSiO3 3SO2 The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu2 S O2 → 2Cu SO2

On the other hand the solubility of copper sulfide in slag decreases as the copper content of the matte increases beyond about 40 . The loss of copper as prills depends on the size of the prills the viscosity of the slag and the settling time available. The most important factors during the smelting process which affects copper loss are
Slabs of impure copper (blister copper) together with thin sheets of pure copper metal or stainless steel or titanium are immersed in a solution of copper(ll) sulfate ( mol dm3) and sulfuric acid (2 mol dm3). The pure copper or steel sheets make the cathode (Figure 7) of an electrolysis cell and the impure slabs are the anode.

In this paper we describe a green solvometallurgical process for the extraction of copper from sulfidic ore minerals
A process for the extraction of copper from a sulphide copper ore or concentrate comprises the steps of subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure to obtain a resulting acidic leach liquor containing dissolved copper and reducing the acidity of the resulting acidic Inquire Now
Copper extraction refers to the methods used to obtain copper from its ores. The 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.
EPC delivers plants for example for producing lysine starch and gluten from cereals oil mills with a cold press or extraction process complete breweries including the brew house and filling plant plants for producing soft drinks and mineral water spirits and liqueur factories as well as plants that produce highquality proteins from
An improved method and apparatus is provided for the production of copper using a solvent extraction electrowinning process. Process streams formed during the process containing entrained liquids are fed to a cyclone (18 23) to remove either organic extractant or water (aqueous solutions) from the stream. A raffinate stream fed to a cyclone (18 23) removes entrained organic phase which
