CiteSeerX — AN IN-PLANT EVALUATION OF FROTH .Traduire cette page

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Column flotation cells have become increasingly popular in the coal industry due to their ability to improve flotation selectivity. The improvement can be largely attributed to the use of froth washing, which minimizes the nonselective entrainment of ultrafine minerals matter into the froth product.
