Heap Leaching

12 · 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. 3 · Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.

Heap Mining Efficiently Leaches Lower Grade Gold …

Heap leaching has emerged as the safest and most efficient ways to mine the lower grade gold that was uneconomical in the past. It is a flexible and continuously evolving extraction technology which gained popularity in the 1980’s when gold prices rocketed from $35 to $800.The model of single heap or complex flowsheet is created from separate blocks, allowing designer to collect sophisticated variants site heap leaching like in tinker toys. Each heap may consist of a set of fractions that differ in their kinetic and hydrodynamic parameters, gold content and exchange constant between the flowing and unflowing areas.
