The number of crushing stages necessary to reduce ore to the proper size varies with the type of ore. Hard ores like gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: crusher selection, crusher layout and process design.
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 …

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 gold extraction process called cyanidation where ... Gold …

and intensive leach circuit only. The circuit incorporates crushing and coarse grinding (often plus 500µm), then gravity recovery followed by intensive cyanidation of the gold concentrate. The gold in solution is then recovered either directly with electrowinning or with activated carbon in columns.
this usually means sacing some gold recovery. The lowest cost gold is normally produced by open pit mining with minimal crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to 95-99% by grinding to fairly fine particle

Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".
