extracton of copper in its ore

In the extraction of Cu, the reaction takes p The sulphide ore of copper is heated in the air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide.Self - reduction of CuS to Cu can be carried out in either Bessemer converter or Pierce - Smith converter. 2Cu2S + 3O2 → 2Cu2O + 2SO2 2Cu2O + Cu2S → 6Cu + SO2

Web search hints: Porphyry copper – Nazca subduction – Global volcanism smithsonian. 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

copper extraction and purification - chemguideExtracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2. Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper.

EXTRACTION OF COPPER - University of TechnologyEXTRACTION OF COPPER IMPORTANT ORES OF COPPER Copper pyrite or chalcopyrite (CuFeS 2). Chalocite (Cu 2 S) or copper glance. Malachite green [CuCO 3.Cu(OH) 2]. Azurite blue [2CuCO 3.Cu(OH) 2]. Bornite (3Cu 2 S.Fe2S 3) or peacock ore. Melaconite (CuO) etc. EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper

Innovations: Introduction to Copper: Mining & Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active

Innovations: Introduction to Copper: Mining & The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

The cathode plates are coated with graphite in order to remove depositing copper. The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity.Bioleaching - WikipediaExtractions involve many expensive steps such as roasting, pressure oxidation, and smelting, At the current time, it is more economical to smelt copper ore rather than to use bioleaching, since the concentration of copper in its ore is in general quite high. The profit obtained from the speed and yield of smelting justifies its cost. Nonetheless, at the largest copper mine of the world
