The metal beryllium is mined by its extraction from the beryl ores. It does not occur free in nature. A relatively abundant metallic element in the Earth's crust, beryllium, has not been widely used due to the high cost of production and its limited consumption. The beryl ore seems to have more content of beryllium compared to the bertrandite ore because of which it becomes an extremely ...
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important byproduct of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Mining costs also vary enormously, and are very much higherfor underground than for openpit operations. ... This is aconcentrate production of kg/ton of ore, at a copper price of £ 980/ton.
Extraction and refining. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 .

Additionally, higher prices can be achieved with the concentrate since the ore content is considerably greater. But larger plants, with integrated recovery facilities, also profit enormously from our ore sorting technology. STEINERT ore sorting solutions complement and reduce the burden on the downstream stages of conventional processing.
Process The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.

Indonesia continues to be a significant player in the global mining industry, with significant levels of production of coal, copper, gold, tin and nickel. In particular, Indonesia remains among the world's largest exporters of thermal coal. Global mining companies consistently rank Indonesia highly in .
Around 18,000 people work at the mine, which is operated by PT Freeport Indonesia, a subsidiary of Freeport McMoran Copper Gold. To support the mine and its workforce PT Freeport has built an airport, a port at Amamapare, 119km of access road, a tramway, hospital, housing, schools and other facilities.
Latest stories. (They will, however, have to pay stiff export taxes, rising from 25% this year to 60% in 2016.) Freeport Indonesia, an Americanowned miner, had warned of a 60% cut in production at its Grasberg mine in Papua, the world's fifthlargest copper mine, if the ban had been imposed in .

Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (% by mass). Ideally, the figure should be closer to 2%. The world's largest copper ore deposits are found in Chile on the west coast of South America. This is due to the volcanic activity that is part of the process that created the Andes mountain chain.
