froth flotation project cost
Froth Flotation Technique Method Procedure
Frothers are the reagents necessary to produce the mineral- carrying froth. The quantity consumed is 1/20 to 1/5 pound per ton of ore. For sulphide flotation various wood oils have been used, the most common being pine oil, particularly steam-distilled. Cresylic acid is a common frother of another type.
