Heap Leaching of Gold and Silver Ores

Original sulfide content is typically 2–3% pyrite, and the gold is often enclosed in the pyrite. Oxidized ores yield 65–85% recovery but may have to be crushed to below 12 mm (½″), although some ores are successfully leached at run-of-mine sizes. Unoxidized ores yield 45–55% gold recovery and nearly always need crushing. 2.1.3.
