Apr 11, 2018As minerals frequently appear in complex associations in nature, liberation, achieved through comminution, is one of the most relevant aspects in ore processing. The global efficiency of a plant often depends on the performance of the grinding circuit, so there is a compromise between particle size, energy consumption and liberation.

It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing plant, including sampling and analysis and dewatering. All these operations are discussed in this article.
