The use of electrochemical measurements in the flotation
The aim of this work was to use mineral potential measurements to gain an understanding of respective mineral flotation performance in the processing 01/06/2002 E h as measured by a platinum electrode is not necessarily reliable for correlating and understanding changes in mineral flotation performance especially in the case of mixed complex sulphide ores This is because it is the potential of the mineral–solution interface rather than the platinum electrode potential that controls the electrochemical reactions occurring at The use of electrochemical measurements in the flotation 24/06/2017 A flotation method using mercaptobenzothiazole collector in an acid circuit was devised for preparing a platinumpalladium concentrate from Stillwater complex gabbro (Montana) Benchscale experiments showed that rougher flotation recovered 91 pct of the platinum and 88 pct of the palladium in a concentrate assaying 26 oz/ton Pt and 88 oz/ton Platinum Palladium Flotation
