to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated. Thermal decomposition is an endothermic reaction.

There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer .

36) Large potatosized nodules found on the sea floor contain manganese, copper, and nickel. What is the main reason these minerals have not been mined? a) it would cost more to mine the minerals than they are currently worth b) international agreements for seafloor mining do not yet exist c) nobody is really sure where these nodules are located

Mineral mining is the extraction of minerals such as coal and precious gemstones. Coal is a significant mining product produced in substantial amounts all over the world.

the vein system implying that copper sulfides at depth may be analogous Butte where to tennantite occurs in the Intermediate Mainstage Zone and enargite in the Central Zone where a higher sulfidation stage existed with advanced argillic alteration. The porphyry copper geochemical signature clearly

Feb 28, 2018· The world's deepest mine is the Mponeng gold mine in South Africa, which extends to a depth of almost 2½ miles below the Earth's surface. Mining is a process of extracting minerals and metals from the Earth.

The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Copper mining has played a key role in the development of South Australia since European settlement in 1836. In particular, the discovery of rich copper deposits at Kapunda (1842), Burra (1845), Kanmantoo–Callington (1846), Wallaroo (1859) and Moonta (1861) were vital to the early development and prosperity of the State.

Now officially a medium sized mining project, the Company can partially turn its attention toward the end product and marketingrelated matters. "The final product from the mine is a coppersilver concentrate, the content of which is 40 percent copper and 347 g/t silver," Rasmussen explained.

Copper, that reddishorange metal that has been used to benefit civilization since 8000 is one of the most important metals used by modern industry. Prized for its ability to conduct heat and electricity, it is an element that helps facilitate the world as we know it, and is a focus of Vale's investment.
