Abstract
Flotation aids, for use in ore flotation and beneficiation processes, comprising polyamines in the presence of fluorosubstituted organic compounds, either mixed therewith or at least partially-neutralized thereby, such that the resulting compositions separate silicate impurities and the like while also modifying and/or suppressing the froth generated. The synergistic nature of such compositions, certain embodiments of which are structurally novel, provide a cost-effective route to higher yields and increased production rates.
