There are many arrangements and combinations using flotation in conjunction with treatment of gold ores The two gold process flowsheets shown, with some variations, are probably the most commonly used In Gold Flowsheet No 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded

M G Aylmore, in Gold Ore Processing Second Edition, 2016 5 1 1 Platsol Process The Platsol process was originally developed in collaboration with the University of British Columbia, Kane Consultants Ltd , and Lakefield Research in Canada for the treatment of flotation sulfide concentrate for Polymet Mining Company in Minnesota and was tested on similar types of concentrate materials

R Dunne, in Gold Ore Processing Second Edition, 2016 6 2 Depression of Sulfide Minerals With Cyanide The depressing action of cyanide on pyrite during froth flotation is well known Sutherland and Wark, 1955 and is widely exploited on many flotation plants to

Gold mineral flotation normally adopts one stage grinding flotation process, but stages grinding and flotation for ore with uneven distribution Grinding fineness of gold For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation but for the gold with gangue, grinding fineness should reach gold monomer dissociation

Froth flotation is considered to be the most widely used method for ore beneficiation In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer
