Froth flotation Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents.The modern froth flotation process was invented in 1901 by C.V Potter in Australia and in 1902 by G.D Delprat in Holland.
attach to the bubbles . This paper examines the washing ability of froth flotation method applied to the fine coal product of Vietnam. In this research, fine coal samples were taken from a major coal preparation plant in Vietnam.
The process of froth flotation is effective for the beneficiating of fine coal <0.5mm. Operation. Fine coal can be separated from shale and other waste by the process of froth flotation.
