Beneficiation of Gold and Silver Ores
Flotation of ore at a top-size of 3 mm, followed by gravity concentration of the flotation tailings, has been applied previously in South Africa to treat Witwatersrand gold ores resulting in the production of a 40% mass pull at an overall gold recovery of 98% (Lloyd, 1979). Coarse particle flotation of particle ranging from 3 to 5 mm is common ...
