Comminution in Mining: Process, Stages and New Technologies

Comminution is a technical term used in mining and metallurgy to refer to the process of reducing the size of rocks or minerals by crushing and grinding. The main objective of comminution is to free valuable mineral particles from gangue (unwanted material) so that they can be processed and recovered in later stages, such as concentration or leaching.

Grade Engineering (G.E) refers to a range of integrated strategies aiming to improve feed grades by removing low grade uneconomic material prior to energy intensive and inefficient grinding (Walters, 2016).In this work the impact of preferential grade by size deportment and differential blasting for grade on comminution circuit performance (throughput) is investigated.

Increasing efficiency by selective comminution

While selective comminution was occasionally applied in processing ores and industrial minerals in the past (Puffe, 1955, Taggart, 1956), a systematic investigation on the process is still missing.A realistic prognosis for new plants based on the comminution behaviour of the various mineral constituents of the ore is therefore difficult.
