Hf Free Flotation Of Feldspar

Nov 01 2016 The role of HF in the flotation of feldspar has been studied by several authors in the past and several possible mechanisms have been proposed (Dean and Ambrose 1944 Graham and Horning 1947 Buckenham and Rogers 1954 Smith and Smolik 1965 Perry et al 1983) In conclusion all reported studies support the suggestion that the feldspar surface could become negative when treated with HF because it seems to remove positive cations from the feldspar surface
