US Patent for Process for leaching copper from copper

Disclosed is a process for leaching copper from copper sulfide using bacteria, which ensures that the rate of leaching of copper increases to reduce the leaching time period and that the rate of leaching of primary copper sulfide contained in ores is increased. The process comprises using an acid leaching solution that includes both or any one of iron oxidizing bacteria and sulfur oxidizing

Copper mining in the United States Wikipedia

Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2021 the United States produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru.Copper was produced from 23 mines in the US. Top copper producing states in 2021 were (in

copper occurs in many lavas that do not have red, oxidized flow tops or interiors. This sulfur deficiency in lavas is in contrast to the situation in mafic intrusive bodies where disseminated copper typically occurs as a sulfide, either chalcopyrite or bornite. Though many exceptions can be cited, native copper is

Origin of sulfur and crustal recycling of copper in

The Great Bear Magmatic Zone, in northwest Canada, contains numerous polymetallic mineral occurrences, prospects, and deposits of the iron oxide copper-gold deposit (IOCG) family. The mineralization is hosted by the Treasure Lake Group and igneous rocks of the Great Bear arc and was deposited concomitantly with the arc magmatism (ca. 1.88 to 1.87 Ga).

Porphyry copper deposits are associated with intrusive rocks and are formed when large quantities of hydrothermal solutions from underlying magma pass through fractured rock within and around the intrusive and deposit metallic minerals along hairline fractures as well as within larger cracks. Porphyries are disseminated, low grade deposits (0.5

Copper-Gold Skarn Mineralization at the Karavansalija

Within the epidosites the sulfide mineralogy is represented by disseminated cobalt-nickel sulfides from the gersdorfite-krutovite mineral series and cobaltite, and pyrite-marcasite-chalcopyrite-base metal aggregates. The skarn sulfide mineralization is characterized by chalcopyrite, pyrite, pyrrhotite, bismuth-phases (bismuthinite and cosalite), arsenopyrite, gersdorffite, and

Chalcopyrite Mineral Uses and Properties Geology

Chalcopyrite serves as the copper source for many secondary mineral deposits. Copper is removed from chalcopyrite by weathering or solution, transported a short distance, then redeposited as secondary sulfide, oxide, or carbonate minerals. Many malachite, azurite, covellite, chalcocite, and cuprite deposits contain this secondary copper.
