5 types of phosphate froth flotation proces
The use of froth in flotation is twofold. first, froth is used to convey the mineral-laden bubbles from the froth–pulp interface to the concentrate launder. second, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp figure 13. the froth cleaning process can be improved by spraying wash flotation.
