Precious Metal Heap Leach Design and Practice OreMax

Oxidized ores leach very well, with low reagent consumption and production recovery of 80% or better. Ores are typically coarsecrushed (75mm) but may show recovery of 70% or better at run ofmine sizes. The largest of the northern Nevada heap leaches (Carlin, Goldstrike, Twin Creeks) treat this type of ore.
