Fine G Recovery by Flotation 911metallurgist

Nov 07, · G Flotation Column. In view of the tendency of fine g recover by floating and the dominance of heavy minerals, the prospects for flotation were worthy of reinvestigation, particularly with the new tools of the air sparged hydrocyclone (ASH) and the flotation column. Although g readily and naturally forms a hydrophobic film, dithiophosphates have been advanced as more selective for g than xanthates and float g
