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.

Mineral beneficiation is the process of separating economically essential minerals from their respective ores. For example, aluminum is extracted from bauxite ore. Ores are the aggregates of rocks from which the desired minerals are extracted. They can either contain minerals or metals that are economically important to humans.
