Roll Crusher
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.
Copper Mining: The commonest ore used in the extraction of copper isChalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore:

The early developmentof copperprobably was most advanced in Egypt.As early as 5000 bce,copperweapons and implements were left in graves for the use of the dead.Definite records have been found of the workingof coppermines on the Sinai Peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art ofextractingthe metal included some refining.

Extractionof Metals.Extraction of Copper..Copperis sometimes found as native metal..Copperores includecopper(II) oxide andcopper(II) sulfide.Copper(II) oxide can be reduced by reaction with carbon.. Somecopperores may contain only small amountsof copper. These are called low grade ores and have less than 1%copperbut they are still used becausecopperis so valuable.
After pre-processing, the ore is leached with acid of alkali solutions to extract the metal. Heap leaching is carried out in theextraction of copper, nickel, uranium and precious metals.
