The new team, led by JKMRC Senior Research Fellow Dr Cathy Evans, has expertise across the mining value chain, with strengths in comminution and mineral processing, CEEC said. Dr Evans' specialty is in understanding how ores respond in mineral processing circuits based on the behaviour of minerals in breakage, liberation and separation processes.

Keywords: comminution; grinding; matrix model; population balance model; particle size distributions; ball mill 1. Introduction Comminution is one of the most important processes of the mining industry and, more specifically, of the materials processing industry. However, it is an energy intensive process, especially at the stage of grinding, and consumes 3–4% of the electricity generated ...
processing operations, including ore blending, circuit design and mill optimization. Most geotechnical tests require large amounts of sample, expensive equipment and are very time consuming. Standard test methods like uniaxial compressive strength and fracture toughness are not considered appropriate in comminution characterization. Alternatively, simple and rapid methods have been used in ...
Finally improved comminution can also be achieved by process optimization on grinding circuit level as well as process plant level. This comprises the introduction of improved classifiion methods within comminution circuits but also the preconcentration by removing liberated gangue already at coarser particle sizes, or by successive separation and size reduction, for instance within staged ...
A double toggle jaw crusher is much larger, heavier, more moving parts and lower throughput than modern single toggle jaw crushers. The lower throughput statement is a bit misleading because it's partially attributed to the type of bearings they have versus modern crushers, so if one was to upgrade the bearings, throughput could be closer .

Efforts for improving efficiencies of comminution circuits have been in many folds, like newer machines and comminution modeling/simulation techniques. Since early 1900s, methods towards economize comminution operations through grindability enhancement studies, like 'Thermally Assisted Liberation' (T A L). The constituents of ore typically have different thermal and mechanical properties, for ...
Mineral comminution circuits : their operation and optimisation. [T J NapierMunn;] Comminution : ALS. Mainly, in order to separate valuable minerals from gangue in mineral processing, the crushing and grinding of extracted ore are crucial operations for the following separation steps. Comminution is the most energyconsuming operation in mining, and the quality of the results is strictly ...
is an important research topic that a mineral processing plant is planned to reach by optimization of the operation conditions. This issue is to minimize the distance of a desired metallurgical performance with real observations in the plant. Despite the considerable investment in the study of this issue and the numerous reported studies, there is a still lack of knowledge about operation ...
