In the heap leach process the crushed ore is stacked over a pit, whose isolation is well provided with special liners. Cyanide solution is fed by means of distribution and dribbling pipes and solution percolates through the ore. The solution loaded with precious metals is sent to the tanks for carbon adsorption. This process is generally preferred for the relatively low grade and higher reserve ores.
