How Extraction of Copper from Copper Pyrites?

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 dissimilar method from silie, carbonate or sulphate ores. The principal ore of copper is copper pyrite and copper is extracted from this ore. Extraction of copper from copper pyrites involves the ...

copper processing

Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper in an ore can .

Extraction of Metals

The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal compound and the impurities and earthly substances called Gangue.

Extraction of Metals from Ores – Different Processes Involved

This step concentrates the ore by performing the removal of impurities. It is also called ore dressing. This process is quite elaborate and is named according to the equipment or technique used. Let us take a quick look. Hydrolytic Method: In this method, the ground ore particles are poured over a vibrating table with a slope or inclination.

Metallurgy

The ore is generally associated with rock impurities like clay, sand etc. called ' gangue or matrix'. The purifiion of ore means removal of gangue from the powdered ore. This process is otherwise called concentration of the ore or ore dressing. Thus, the percentage of the ore in the concentrated ore is higher than that in the original ore.
