MEI Blog: Report on Physical Separation '19

Jun 09, 2019 · Bernard described how the effect on coarse gangue rejection by using single and multi-stage precise impact breakage techniques was investigated. It was found that subsequent stages of precise breakage reduce the amount of valuable minerals in coarse particles and has the potential to improve the outcome of early coarse gangue rejection.

Mineral veins exposed at the surface will be weathered, during which ore minerals are broken up by mechanical weathering or left as insoluble material by chemical weathering separating the ore and gangue minerals. The material is then transported, concentrated and sorted according to grain size, hardness and density by the action of flowing water.

The Cobalt-Gowganda Silver Mining Area

One of the unique things about the Cobalt mining camp is that the mineral wealth was so easily accessible. Veins consisting largely of native silver, argentite and other silver minerals were mineable right at surface. Although, the country rock was very hard, the veins were soft and weathered.

Mineralogy & Flotation: Floatability VS Selectivity Test ...

Mineralogy is the driving force behind flotation performance. A flotation batch and rate test measures this as mass pull recovery and concentrate grade. The real data from a rate test can be processed to determine the flotation kinetics of metal, mineral and gangue. What we cover here is what are kinetics and what do they mean. Special attention is paid to the definition of floatable gangue.
