   Description:

Chalcopyrite , Can identified from its color and streak ,it similar to Pyrite, But the hardness less than pyrite,pyrite’s hardness is 6-6.5,it similar to gold, but higher hardness than gold, Brittle than gold,gold’s hardness is 2.5-3,it same as pyrite, In the field can easily be mistaken for gold,thus name(fool’s gold),chalcopyrite is the main raw material for Smelting copper.

Causes of occurrence

  Chalcopyrite is widely distributed, Can be formed under various conditions, There are several types of : Magmatic: With the basic and ultrabasic rocks related to Cu-Ni sulphide or vanadium titanium magnetite bed, The formation of higher temperatures, With pyrrhotite, pentlandite in close symbiosis, Contact metasomatic:  Chalcopyrite often filling accountable or transparent gray garnet and other minerals mining,With magnetite, pyrite, pyrrhotite and other symbiotic
