· The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis (electrowinning) for low grade ores, or by the carbon reduction method of smelting for higher grade ores. The process of extracting copper from higher grade sulfide ores involves:
An ore is a rock that has enough metal in it to make it worth extracting the metal. The main ores of copper are: Chalcopyrite Bornite Malachite Over 50% of the World's copper comes from chalcopyrite and bornite. Picture 3. Photo of a lump of native copper. Native copper Copper is an unreactive metal it reacts only slowly with the atmosphere.

Solvometallurgical process for extraction of copper from . Abstract 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 .
Copper Extraction. Copper is a reddish orange bright metallic substance that is an excellent conductor of heat and electricity. It can be drawn into pipes and it is resistant to corrosion. The most common found copper ore in nature is chalcopyrite which is a mixed ore of CuFeS 2. It contains only % Cu by mass.
Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silie, carbonate or sulphate ores. Generally, the method used for the extraction of copper from its ores depends on the nature of the ore.

· Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (, via froth flotation). Figure 1: Chalcopyrite extracted from Zaecas, Mexico.
In the present study bioleaching of copper from its lowgrade chalcopyrite ore using 26 isolates of acidophilic fungi is reported. Most of these fungal strains belonged to the genera Aspergillus, Penicillium and Rhizopus. 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 .
