Heap leaching - Wikipedia

This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores, as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.

Sol: Gold and silver ores are concentrated by leaching. In this method, we treat the ore with a suitable reagent in which ore is soluble but impurities do not. Thus, impurities are removed by filtration. Among galena, copper pyrites, cinnabar and Argentine, Argentite being silver ore is concentrated by chemical leaching method.
