Does porphyry contain copper?

It is estimated that the Earth’s porphyry copper deposits contain approximately 1.7×1011 tonnes of copper, equivalent to more than 8,000 years of global mine production.

What are the different types of gold ore?

Eight mineral types of deposits have been determined, which characterize the main gold-bearing mineral ore parageneses: gold-polysulfide, gold-quartz, gold-telluride, gold-tetradymite, gold-antimony, gold-bismuth-sulfosalt, gold-pyrrhotite, and gold-fahlore.

Where is porphyry copper found?

Large porphyry copper deposits are worked in the southwestern United States (where molybdenum is produced as a by-product), the Solomon Islands, Canada, Peru, Chile, Mexico, and other parts of the world.

What are the three forms of copper found in nature?

In nature, copper occurs in a variety of minerals, including native copper, copper sulfides such as chalcopyrite, bornite, digenite, covellite, and chalcocite, copper sulfosalts such as tetrahedite-tennantite, and enargite, copper carbonates such as azurite and malachite, and as copper(I) or copper(II) oxides such as …

What rocks contain copper?

Copper is found in many minerals that occur in deposits large enough to mine. These include: azurite, malachite, chalcocite, acantite, chalcopyrite and bornite. Most copper comes from chalcopyrite. The world’s leading producer of copper is Chile, followed by the U.S. and Peru.

What is copper ore?

The principal copper ore mineral is chalcopyrite (CuFeS2), which is commonly smelted to yield a matte containing ~50% copper.

What is the most common copper compound?

Copper compounds and minerals are often green or blue. The most common minerals include malachite, a bright green carbonate, and azurite, a blue-green basic carbonate. Among the major copper ores are cuprite, CuO, chalcopyrite, CuFeS2, and bornite, Cu5FeS4.
