In the extraction of copper from its sulphide ore, the

In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal. Cu 2

Direct extraction of copper from copper sulfide

Copper is predominantly recovered from sulfide ores by pyrometallurgy an energy intensive process requiring capture and treatment of released SO 2. Whilst some copper ores are amenable to hydrometallurgy, chalcopyrite, the main copper mineral, is challenging to process in aqueous solutions due to surface passivation.

Copper Mining and Extraction Sulfide Ores

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore

min ing and e traction of copper from its ores flowchart

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

Copper Mining And Extraction Sulfide Ores. The froth is skimmed off the surface and the enriched ore mainly the copper mineral is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25 copper by mass and is called copper concentrate. Online Chat

Name the sulphide ore of Copper. Describe how pure

The extraction of metals from ores involve three major steps: 1. Concentration of the ore, 2. Isolation of the metal from its concentrated ore, and. 3. Purification of the metal. For sulphide ores, Froth floatation method is used to concentrate the ore by removing gangue particles from it.

Sulfide Ores an overview ScienceDirect Topics

Cobalt–copper sulfide ores are being exploited in several Democratic Republic of Congo and Zambia mines (Katanga, 2010). Cobalt and copper are extracted in the following steps: (a) flotation; (b) sulfation roasting; (c) leaching (sometimes along with additional oxide concentrate or ore); (d) solvent extraction separation of copper from cobalt; (e)

The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper that is cast into slab-like anodes. Principal impurities are iron and precious metals (gold and silver).

How Is Copper Obtained From It Ores? Blurtit

Copper is commonly extracted from sulphide ores such as chalcopyrite. Chalcopyrite is also known as copper pyrites. The chemical formula for chalcopyrite or copper pyrites is CuFeS2, which means that chalcopyrite is a compound made up of three elements, namely copper, iron and sulphur.
