- froth floatation in desulfurization
The froths produced in pulp-body-concentration processes are small-bubble, coherent and persistent, and characteristic. The volume of gas effectively utilized in floating the mineral is. of the order of 20 to 50 cu. ft. per cu. ft. of solid floated. 1 The general rules follow: 2 The variables affecting froth flotation.
