HOW TO WORK THE HEAP LEACHING

Heap leach is a method developed by Henin and Lindstrom to process low-grade ore on a large scale with small production cost so that the levels below the cut-of grade can still be economical. Heap leach is the process of leaching of low grade gold rocks thrown, then the solution containing the metal particles are screened and separated by electrolysis. Heap leach done repeatedly and on a large scale.

There are several steps that are used in processing gold ores using heap leaching system

HEAP LEACHING Processing System

Heap leaching process was developed as a mineral processing low-grade metal that is more efficient and minimal cost. Compared with conventional cyanidation process of the mineral leaching process with stirred tank Heap leaching has several advantages in the form of designs that use a very simple, operating costs are also minimal, and in requiring less investment, because the heap leaching recovery is around 60% to 80 %. In large-scale process technology was first used and applied to the mining of gold ore at Carlin Nevada USA in 1970. This process has really made ​​a lot of mines that can easily take on geological resources that have a low grade and transforming them into the category of proven ore. Ore value as low as 0.01 oz Au can be processed by heap leaching system is economically.
