process of formation of copper ore

Cobalt and copper metals or chemicals are produced by first reductive leaching. After leaching, the resultant solution is separated from unleached solids and transferred to solvent extraction. Copper and cobalt are separated from each other, leaving cobalt in the aqueous raffinate. This contains impurities such as iron, aluminum, manganese and copper

    First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning)

    The ore is first broken and set out on leach pads where it is dissolved by a sulfuric acid solution to leach out the copper. The copper-rich solution is then pumped to the solvent extraction plant to separate the copper as a copper complex. This is concentrated and the solution is passed to the electrowinning plant to recover the copper

    Mar 30, 2020 · The process of crystallization makes the rock shrink, forming cracks, and the fluid that is left moves into those cracks. By this point, the fluid contains a great deal of copper, so by the time it solidifies, it is almost pure copper. The deposits appear when the rocks on top of them erode, exposing the copper to mining operations

    Key features of giant ore deposits. New computer simulations by geologists from ETH Zurich demonstrate how large copper and gold deposits are formed. The enrichment process of these metals follows physical principles that are similar to the extraction of deep geothermal energy by hydraulic fracturing of the rock
