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 .

Dump and Heap Leaching - HydroJex

for successful heap leaching of gold and copper are provided in the chapters on gold, silver, and copper hydrometallurgy elsewhere in this handbook. Other metals of interest in heap or dump leaching include uranium, nickel, cobalt, zinc, and recently, some rare earth elements. Of these, uranium heap leaching has had the most attention.

Precious Metal Heap Leach Design and Practice

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.

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

free circulation of the leaching agent. The leaching period is 2 – 4 days and gold recovery lies in the order of 70 – 80%. The cheapest but slowest technique is heap leaching. It is a process usually applied to low grade gold ore. Basically the ore is piled to a given height on an inclined impermeable surface, a so called leach pad.

The process design of gold leaching and carbon-in-pulp circuits

takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: 1 Although air agitated leach tanks were commonly used in
