Ore Processing Challenges in Gold Operation Grinding Circuits

Get Price

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.

When looking at overall crushing circuit design, having the correct number of crushing stages also helps minimize fines production. A typical crushing circuit will generate a reduction ration between 5:1 and 7:1 for maximum efficiency. For example, to generate a 10mm particle, you’ll want to feed the crusher particles between 50 and 70mm.
