The influence of multivalent cations on the floatability of scheelite, fluorite and calcite

Abstract

The physicochemical properties of the mineral interfaces of CaWO "SUB 4" , CaF "SUB 2" and CaCO "SUB 3" in the presence of multivalent cations (Ca(II), Mg(II), Al(III)) during the flotation process were investigated. Flotation experiments, zeta potential and ESCA measurements were made for the characterisation of the mineral surfaces and the utilisation of different kinds of zeolites in the flotation systems was examined.
