- Copper Ore Crushed Properties In Afghanistan
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Crushed ore agglomeration has been successfully utilised as a pretreatment step and has two major aims: (1) to allow thorough application of leach solution and "kick start" the leach process, and (2) the application of leach solution or binder allows fine particles to coalesce onto larger rock particles and reduce segregation (Wang et al ...

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 …
