Porphyry copper deposits represent an important resource and the dominant source of copper that is mined today to satisfy global demand. [6] Via compilation of geological data, it has been found that the majority of porphyry deposits are Phanerozoic in age and were emplaced at depths of approximately 1 to 6 kilometres with vertical thicknesses on average of 2 kilometres.

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.
Since copper is an excellent thermal and electrical conductor among engineering metals (second only to silver), [149] electrical systems that utilize copper generate and transmit energy with high efficiency and with minimum environmental impacts.
Porphyry deposits account for most of the copper and molybdenum world production, 60 and 95 percent of its supply respectively. [1] Porphyry-type ore deposits form in hydrothermal fluid circulation systems developed above and around high-level, subvolcanic felsic to intermediate magma chambers and/or cooling plutons. The ore is temporally and ...
When “clean energy” relies on the extraction of metals like copper, it can also pollute the surrounding environment.
Solar thermal heating and cooling energy systems rely on copper for their thermal energy efficiency benefits. Copper is also used as a special corrosion-resistant material in renewable energy systems in wet, humid, and saline corrosive environments. Copper is a sustainable material that is 100% recyclable and has a higher recycling rate than ...
