The product size from a primary crusher is limited by the possible reduction ratio, which normally is around 10:1. The feed size to a primary crusher from the mines could be 1–1.5 m; thus, the maximum product size possible is 10–15 cm which is normally too large for down stream processing for mineral liberation.

Preg-robbing is an important phenomenon that inhibits gold recovery due to the presence of naturally occurring carbonaceous matter. In case of certain ores, gold recovery by cyanidation is limited by the presence of naturally occurring carbonaceous material that adsorbs gold from alkaline cyanide solution unless steps are taken to prevent this adsorption reaction …
