    Precious Metal Heap Leach Design And Practice

    Precious Metal Heap Leach Design and Practice Daniel W. Kappes1 ABSTRACT Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods.
