leaching gold quartz ores

Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from lowgrade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the goldcontaining solution is leached.

Several different permutations of diagnostic leach tests depend on specific objectives, but they generally involve the sequential leaching of a gold ore sample with progressively stronger reagents, producing a qualitative assessment of the gold deportment within the sample.

Heap leaching can take anything from a couple of months to several years. In the case of gold recovery, heap leaching generally requires 60 to 90 days to leach the ore, compared to the 24 hours required by a conventional agitated leach process. Gold recovery is also usually only 70% compared with 90% recovery in an agitated leach plant.
