Electrophoretic mobilities of aqueous dispersions of pure graphite flakes, pure calcite mineral and pure quartz mineral were determined at a given ionic strength and at different pH's, in the absence and presence of additives. The calculated zeta potentials for the different systems were plotted against pH to understand the conditions of flotability/wettability.
