innovations: introduction to copper: mining & extraction

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores

Most copper leaching is done by piling broken ore (0.5% Cu) into flat-surface, 310m high, 10 4 10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 15kg Cum 3

a review of the beneficiation of copper-cobalt-bearing

Nov 01, 2019 Sulphidisation followed by flotation is the preferred beneficiation technique for oxidised copper-cobalt ores. The integration of CPS systems into the flotation circuits can help minimise reagent overconsumption. Application of selective flotation can help a concentrator to produce separate oxide and sulphide concentrates

Bulk ore sorting methods include: Prompt gamma neutron activation analysis (PGNAA) used for sorting bulk materials such as limestone and iron ore. Magnetic resonance, which can be used to sort chalcopyrite from waste minerals. Pulsed fast thermal neutron activation (PFTNA) used for sorting iron ore, copper and nickel

Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction

copper mining and extraction sulfide ores

copper mining and extraction sulfide ores

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers

Sep 26, 2019 Sulfide Copper Ores . Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic
