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 …

Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced each year is recovered by this technique. The advantages and disadvantages of gravity separation are similar to heap leaching. It is a very simple and low cost process, but gold recovery is usually low

African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80% passing 75µm) to ensure that all non-refractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the ...

Stages 1 and 2: Bashing and Mashing. Traditionally, the process selection choice was between a conventional, well-tried, three-stage crushing circuit followed by ball-milling, or single-stage crushing followed by a Semi-Autogenous (SAG) mill and ball mill. The latter is preferred for wet sticky ores to minimize transfer point chute blockages ...
