Copper Ore
Copper ore usually contains about to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.

Copper Extraction and Purification
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 sulfate ores. Getting Copper from Chalcopyrite, CuFeS 2 Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Extraction Of Copper From Copper Pyrite
201248The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.

Then electrolytic refining of copper is carried out to remove the rest of the impurities present in the ore. The impure copper is made anode and strip of pure copper are made cathode. On passing the current as shown in the diagram, the pure copper from the anode dissolves into an electrolyte. An equivalent amount of copper is deposited on the

Copper extraction
Copper extraction refers to the methods used to obtain copper from its 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.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Bioleaching of copper from chalcopyrite ore by fungi
The leaching experiments were conducted in Czepek Dox minimal medium containing 1% (100 mesh) ore with shaking at room temperature for 20 days. Out of these, 4 isolates exhibited significant bioleaching activities. Maximum leaching of copper (78 mg/L) was observed with Aspergillus flavus (DSF8) and Aspergillus niger (DOF1).

How is copper refined from its ore?
The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. How is copper ore refined? In fire refining, air and natural gas are blown through the copper to remove any remaining sulfur and oxygen, leaving refined copper behind to
