Common extraction processes for copper ore mining pedia,nov 08, 2019 in-situ leaching process can be used to treat the residual ore of old mines or the unmined oxidized copper ore and lean copper ore. in-situ leaching process has better potential than other processes for those abandoned mines or uneconomical copper mines with other processes.
Jaw crusher is widely used in crushing the medium particle size materials of varieties of minerals and large materials, and it is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and other industries.
Impact crushers are also known as impact breakers or impact crushing machines. It can crusher the material whose side length is below 100-500mm and highest compressive strength can reach to 350Mpa.
Cone crushers are also known as cone breakers. Compressive strength of cone crusher is no more than 250MPa. Cone crusher is widely used in mining, metallurgy, building materials, chemicals and other sectors to crush hard and medium hard materials.
Sand maker is also known as impact crusher or sand making machine. It is a kind of equipment with high technology.
Sand washer is also called sand washing machine. It is the necessary equipment for washing sand making.
Ball mill is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industry.
The wheel-mounted mobile impact crusher as a kind of mobile impact crushing plant adopts the star product of our company: the impact crusher. As a leading rubber-tyred mobile impact plant
Charcoal briquette machine is also known as charcoal briquetting machine, charcoal ball press machine, or charcoal pressure ball machine.
Rotary screen is mainly used for sieving big or small stones, separating soil and gravel, coal blocks and coal powder, etc. It can also be called gravel screen or stone separator. Since roller device is composed of filter screen, it is also called rotary sieve.
Hammer crusher is composed of chassis body, rotor, hammer, back liner, sieve, etc.. It is suitable for conduct coarse, medium, fine crushing for materials with the compressive strength less than 180MPa like limestone, coal, gypsum, shale and other types of brittle materials.
Roll crusher (roller crusher) is suitable for the fine crushing of the materials with feeding size less than 110mm, and finished particle size 3-30mm.
Compound crusher is also known as combination rock crusher. Compound crusher is mainly used for medium or small cement or clinker crushing.

nov 08, 2019 in-situ leaching process can be used to treat the residual ore of old mines or the unmined oxidized copper ore and lean copper ore. in-situ leaching process has better potential than other processes for those abandoned mines or uneconomical copper mines with other processes.the techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. the oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.hours ago the heap leaching technique was first used for precious metals recovery in 1969 at the cortez gold mine where it proved highly-efficient at improving recoveries from near-surface oxidized ore quoted operating costs based on current technology for leaching dumps and in-place ore, are between us$0.18 and us$0.22 per pound of cathode copper, which are competitive with the unit costs of smeltingrefining. heap leaching has the additional cost of mining and transporting to the leach pad.
