Heap leaching is an industrial mining method to dig out precious metals and copper compounds from ore. Process of heap leaching The mined ore is crushed into tiny chunks and heaped on an impermeable plastic and/or clay lined leach pad where it may be irrigated with a leach solution to melt the valuable metals.

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficulttoconcentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electrowinning (EW). It can produce either copper cathode or copper sulphate crystal.

According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide. Copper sulfide ore flotation

Heap 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 reseparate 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 the ...

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 SXEW (solvent extraction/electrowinning).
