Chalcopyrite
Chalcopyrite is a conductor of electricity.
Copper can be extracted from chalcopyrite ore using various methods. Chalcopyrite can be oxidized to form malachite, azurite, and cuprite.
Structure
Chalcopyrite is a member of the tetragonal crystal system.

triazolate anions link the octahedra
Association
Chanabayaite coexists with halite, joanneumite, nitratine, salammoniac and paragenetically-unrelated chalcopyrite Chalcopyrite is present in an amphibole- and plagioclase-bearing gabbro, that contacts the guano deposit.

Cubanite
It results from exsolution from chalcopyrite at temperatures below 200 to 210 °C. The ores that are associated with cubanite are unaltered pyrrhotite-pentlandite-chalcopyrite ores that experience alteration to millerite-pyrite-chalcopyrite-cubanite

US4201748A - Process for thermal-activation of chalcopyrite-pyrite ...
A process for thermal activation of chalcopyrite-pyrite ore concentrates for activation of iron values in both chalcopyrite and pyrite constituents whereby said iron values can be selectively removed in a subsequent acid leach. Controlled oxidizing conditions are maintained in an oxidizing heating zone for removal of up to about 90% of total sulfur to be removed for conversion of pyrite and ...

Bornite
Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits. Exsolution of blebs and lamellae of chalcopyrite, digenite, and chalcocite is common.

Pentlandite
A separate phase, usually a copper-rich sulfide liquid may also form, giving rise to chalcopyrite upon cooling. Pentlandite, but primarily chalcopyrite and PGEs, are also obtained from the supergiant Norilsk nickel deposit, in trans-Siberian Russia.
