Ore Processing Challenges in Gold Operation

16-06-2020  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.
