Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits.
The proportions of carbonate, shale and sandstone ore types vary from mine to mine and the ore horizon ranges from to 20m in thickness, lying at depths of between 600m and 1,200m from surface. The overall average thickness in the mineable zones is Chalcocite, bornite and chalcopyrite are the most important minerals.

ndida copper, gold and silver production. Production at the mine was cut back during the period 2003 on account of the weak world market conditions for copper. The partners in the project decided to mine lowergrade ores while maintaining the concentrator throughput, thus reducing the impact on pertontreated costs.
The Ann Mason deposit has the characteristics of a typical, large coppermolybdenum porphyry system. Projected to the surface, the % Cu envelope covers an area approximately km northwest and up to km northeast.
The mining method is leaching in place (in situ). Mine capacity in 1978 was 2650 liter soln/min with a production unit cost of 0 /mt ore. The ore mined is composed of bornite, malachite and azurite.
Within the hydrothermal deposits, bornite associates itself with chalcopyrite, pyrite, sphalerite, flore. Within the zone of oxidation, at the expense of bornite, there form themselves malachite, azurite, cuprite, and other supergene minerals. Bornite is the important mineral of the copper ores. The major method for beneficiation is flotation.
Originally included with kupferkies in 1725 by Johann Friedrich Henckel. Later assigned various multiword Latin names by Johan Gottschalk Wallerius in 1747 and variously further translated including "purple copper ore" and "variegated copper ore" in 1802 by Rene Just Haüy.
