Chat Onlinea copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal.A typical copper ore contains between 0.5% and 2.0% copper.A high grade ore produces a high yield of metal.A low grade order produces a .
Chat Onlineheap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials.Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to .
Chat Onlinethe ore is treated with dilute sulphuric acid.This trickles slowly through the ore dissolving copper to form copper sulphate.The copper is recovered by electrolytic refining.Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off.
