Heap Leaching of Gold and Silver Ores ScienceDirect

Where the ore is high in silver, typically with a recoverable silver content of more than 10 g/t (0.3 oz/ton) of ore, Merrill Crowe zinc precipitation is used instead of carbon adsorption. In this process the solution is clarified and de aerated, then contacted with zinc dust to precipitate metallic gold and silver.
