Percolation Heap leaching, (see Mular et al. pp. 15711630, loc. cit.) is very widely applied to the ores of copper and precious metals, but percolation is also conducted on a smaller scale in batch tanks or vats and in continuous or dump extractors. In the heap leaching of lowgrade oxidized gold ores, for instance, a dilute alkaline solution of sodium cyanide is distributed over a heap of
