2020-11-9 · The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises ...

Minerals | Special Issue : Gravity Concentration

Gravity concentration is at present the main concentration process in the mineral industry in terms of tons processed. The size that can be processed ranges from very coarse materials, coarser than 100 mm, concentrated through heavy media vessels or ROM jigs, to very fine particles, about 10 microns, concentrated through centrifugal processes.
