Cuprumis Latin language, it is also known as well know mineral copper. Copper is one of the world's most important industrial minerals; and Africa is an important world producer. While output is traditionally dominated by Zambia, South Africa and Congo, many African nations contribute to copper production.
Mining in South Africa has been the main driving force behind the history and development of Africa's most advanced and richest economy. South Africa is endowed with minerals resources, such as gold, diamond, coal, copper etc. Copper is one of important minerals in South Africa. Cuprum mining in South Africa is operated by open pit and underground mining methods.
Copper is commonly extracted from surface, underground mining methodand increasingly, from in situ operations.
Surface cuprummining requires extensive blasting as well as rock, soil, vegetation, and overburden removal to reach lode deposits. Benches are cut into the walls of the mine to provide access to progressively deeper ore as upper-level ore is depleted. Copper ore is removed from the mine and transported to beneficiation plants for milling and concentrating. The concentrate is then smelted and refined. Open-pit mining is the primary domestic source of copper.
Underground mining entails sinking a shaft to reach the main body of ore. Drifts or passages are then cut from the shaft at various depths to access the ore, which is brought to the surface for beneficiation. While underground mines do not create the volume of overburden associated with surface mining, some waste rock must still be brought to the surface for disposal. Waste rock may either be returned to the mine as fill or put in a disposal area.
The copper ore extracted from the mine must be processed by mining plant and concentrated by beneficiation equipment. The valuable minerals like chalcopyrite are inter-grownwith gangue. Therefore, in the first step in cuprum mining plant in South Africa, the lumpy ore is crushed and milled into fine particles and prepared for further mining operation.Copper mining plant in South Africa for sale includes crushing plant, grinding mill, vibrating screen, separation machine, quarry plant etc.
The primary crusher in copper crushing operation is jaw crusher. Typical equipment for crushing to about 20 cm is gyratory crusher, cone crushers and impact crushers. Then wet grindingin grinding mills takes place. Size classification takes is performedin cyclones. In the next step of mining plant, valuable minerals and gangue are separated by frothflotation of the ore pulp, which exploits the different surface properties of the sulfidic copper oreand the gangue.
In open pit copper mining operation, crushing is the first processing stage. Copper ore crushing may be performed in two or three stages. Primary crushing circuit consists of crushers, feeders, dust control systems, and conveyors used to transport ore to coarse ore storage or further crushing plant. Primary crushing is generally processed by a jaw crusher or gyratory crusher, since these units can handle larger rocks.
The feed to primary crushing is generally run-of-mine ore, which is reduced from large pieces to smaller pieces. Secondary and tertiary crushing usually is performed in surface facilities in cone crushers, although impact crusher or hammer crusher are sometimes used.
