Minerals Engineering Conferences

Comminution '10 was organised by Minerals Engineering International (MEI) in consultation with Prof Malcolm Powell.. In 1997 Prof Malcolm Powell formed the comminution group at the University of Cape Town, following the suggestion of Prof Cyril O'Connor (director of the Mineral Processing Research Unit MPRU) -after a memorable MEI conference in Cornwall.

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.

Optimizing Comminution | Engineering article

According to the report from Minerals, comminution in mining consumes up to 1% of total final energy consumption globally — equivalent to the power consumed by 221 million typical U.K. homes. This makes comminution circuits, both new and existing, a priority area for optimization, as small improvements can lead to large energy savings.
