extraction of copper from copper matte

Extraction Of Copper Mining, Concentration, Smelting

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. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper

use of SiO2 in the extraction of copper from copper matte

6 years ago. Silica (SiO2) is used in the processes of smelting of copper pyrite (CuFeS2) ore and in conversion of produced copper matte (refined copper sulfide) into a crude metal as a flux (purifying agent). It reacts with solid impurities, such as iron oxide, and forms a liquid slag with density, smaller than the copper matte.

METALLURGY OF COPPER-EXTRACTION OF COPPER

2012-7-24  Copper metal is extracted from molten matte through bessemerization . The matte is introduced in to Bessemer converter which uphold by tuyers. The air is blown through the molten matte. Blast of air converts Cu2S partly into Cu2O which reacts with remaining Cu2S to give molten copper. 2Cu2S + 3O2 è 2Cu2O + 2SO2.

In the extraction of copper, the copper matte is a mixture of:

The chemical formula of copper matte is Cu 2. . S+FeS. It is a combination of copper sulphide and iron sulphide. It is a phase in which extracted metal is converted into crude metal which is a final product. 80−70% of copper matte is used 80−95%. 5−17% metallic copper, Fe−Co alloy etc are used.

the copper matte. Though, the slag can be easily separated from the desired product. Smelting is an exothermic reaction between copper pyrite ore, oxygen of air and fluxes (such as silica and limestone) at 1200 °C (above the melting point of copper, but below that of the iron and silica) to form a liquid called "copper matte".

Solvometallurgical process for extraction of copper from

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
