Gold recovery in comminution circuits | Henan Deya .

In plants with free-milling gold, this leads to gold concentrating in the milling circuits (see attached). On a size-by-size basis, concentrations of up to 100 times can occur in cyclone underflow. In this respect, hydrocyclones are outstanding rougher concentrators.

Ore Processing Challenges in Gold Operation Grinding .

Comminution circuits are used to optimize the liberation of valuable mineral particles from waste rock for downstream separation processes. When the target grind is not achieved (under-grinding), it results in a higher number of unliberated gold particles. This in turn causes a loss in gold recovery and therefore revenue.

1/1/2005· Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.
