Mining - Wikipedia
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.Exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who3 Technologies in Exploration, Mining, and Processing,,Comminution (i.e., the breaking of rock to facilitate the separation of ore minerals from waste) combines blasting (a unit process of mining) with crushing and grinding (processing steps). In-situ mining, which is treated under a separate heading in this chapter, is a special case that combines aspects of mining and processing but does not,Gold mining - Wikipedia,Gold mining is the extraction of gold resources by mining.Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning.However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation.In the 20th and 21st centuries, most volume ofCopper Mining and Processing: Processing Copper Ores,,Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively,4 Coal Mining and Processing | Coal: Research and,,The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity.
