Minghua vane flotation cell

Feb 19, 2021

Feb 01, 2015 The importance of froth rheology in evaluating flotation performance and modelling froth transportation zone has been previously recognised (Farrokhpay, 2012a).Moudgil (1993) observed a direct correlation between froth viscosity and flotation recovery and, on the other hand, an inverse correlation between froth viscosity and the phosphate mineral grade (in
