Metallurgical ContentLearn CyanidationDevelopments in the Carbon-In-Pulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a ...

Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with applications growing all the time. While this process has proven to be efficient, often chosen for its cost-effectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum .
· Heap leaching has become a popular method of extracting gold, writes Nicolaas C. Steenkamp and Leon Louw. 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 …
Gold recovery using the heap-leach method is based on the process of applying a leachate that usually contains about 100 to 600 parts per million (ppm) (0.01 to 0.06 percent) NaCN in a water-based solution to a large pile of crushed or run-of-mine rock and, occasionally, mill tailings (Hoye, 1987; van

· Large-scale gold and silver heap leaching began with the first Cortez heap leach in 1969. While many projects have come and gone, Cortez is still going. Nevada was the "birthplace" of modern gold heap leaching in the late 1960s, and is only recently giving up its dominance of this technology.
Once the leach solution dissolves the gold, it continues percolating through the lower lifts until it reaches the liner located underneath the heap. Then it drains into a storage pond. Most economical heap leach mines achieve 70-80% recovery of gold and 30-50% of silver.
Operations at CC&V consist of open-pit mining followed by heap leaching on a valley-fill-type heap that provides the sole means of gold production. Heap leaching operations at the Valley Leach ...

The first major gold and silver heap leach was the Cortez (USA) heap leach in 1969 which is still operating and was expanded to 63,000 tpd in 2002. 1.2. Fundamental Cycle The simplest flow diagram of a percolation leach system is one in which the leachate ...
Heap leach mining is an industrial hydrometallurgical process, where the metal contained in an ore body is extracted by dissolution. The target mineral is leached with an aqueous solution whereby the mineral is dissolved into what is called a "pregnant" solution which, is then captured and later recovered downstream in the processing line.
