Abstract

Abstract To reduce environmental and occupational impact of flotation reagents, there is an emerging need to find greener reagents for sulphide mineral flotation. This study presents a comparison of the interactions of chalcopyrite with three glycolipid biosurfactants (sophorolipid, glucolipid and glucoside) and three traditional thiol surfactants (collectors) to assess the potential of the biosurfactants as collectors. The mineral-surfactant interactions are studied using adsorption isotherm, zeta potential, FTIR spectroscopy and flotation tests. We find that glycolipid biosurfactants hold high potential as collectors for flotation of copper sulphides.
