Process Design, Scale-Up And Plant Design For Gravity Concentration

The role of gravity separation in the mineral industry is briefly considered in perspective. The mineralogical and laboratory approaches to gravity process design are examined with emphasis on process technology selection. The equipment available for small scale and pilot test-work is discussed, particularly in regard to scale-up and the acquisition of reliable, accurate data. Transposition of performance data from pilot scale to plant scale is explained. The available types of full scale gravity separation equipment are discussed with emphasis on large high-capacity units. Plant layout and selection of ancillary equipment are considered.
