FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

The main disadvantage is that gold recovery is generally lower than that achieved by grinding to a finer size and leaching in stirred tanks. In addition, the rate of leaching is slow and recoverable gold can be held up in the heap for months, which impacts cash flow. There can also be longer term environmental liabilities associated with heap .

Estimated Water Requirements for Gold Heap-Leach Operations

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
