Estimated Water Requirements for Gold Heap-Leach

2012-12-20 · The Heap-Leach Process Briefly stated, gold heap leaching is a hydrometallurgical process designed to treat amenable low-grade gold ores that contain roughly 0.5 gram per metric ton (g/t) gold to 1.5 g/t gold (Marsden and House, 2006; Wong Wai Leong and Mujumdar, 2010). The ore is stacked by various types of equipment

Heap leaching a stack of gold MiningFeeds

2018-4-25 · Heap leaching is used to extract gold, copper, silver, uranium, and iodine. This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s, and then by several gold mines in the western parts of the US a few years later. Since then, heap leaching has been adopted successfully by many mines across the world.
