Aug 04, 2016· The ability to use heap leaching, together with solvent extraction and electrowinning (SX/EW) to go from ore to high grade metal at the mine-site, makes it
The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. mo

2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3–10m 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 1–5kg Cum −3.
A leaching solution of weak sulphuric acid is sprayed over the rock on the pad and allowed to percolate through to the base. As the solution passes through the heap, the copper-bearing mineral dissolves into solution. The copper-bearing solution accumulates in the collection pond and is piped to a nearby SX-EW plant for metal recovery. Leaching

Copper heap leaching plant manufacturers heap leaching heap leaching is an industrial mining process to extract precious metals copper uranium and other compounds from ore via a series of chemical reactions that absorb specific minerals and then Copper heap leaching plant manufacturers.
In the United States, for example, the energy requirement for SX/EW processing of heap or dump leaching ranges from an estimated 10 MJ/kg to 25 MJ/kg the difference being largely the pumping costs. In the case of the higher energy consumer, the pregnant liquor is pumped five miles from the leach site to the SX/EW plant.
