According to the methods of formation and morphology of the ore bodies and the composition, several industrial types of copper ore are distinguished (see Table 1) In terms of the reserves and extraction of copper, porphyrytic ores (porphyry copper) account for the largest share—more than 60 percent of known reserves and 40 percent of world production (excluding the socialist countries)

Bornite Wikipedia

Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite Composition Substantial variation in the relative amounts of copper and iron is possible and solid solution extends towards chalcopyrite (CuFeS 2) and digenite (Cu 9 S 5) Exsolution of blebs and lamellae of chalcopyrite, digenite, and chalcocite is common
