Abstract
Flotation tests for quartz and alumina were carried out using sodium N-coco-B aminopropionate and g-y Dipal mitoyl L—a lecithin as collectors. In some systems, good flotation of a mineral occurs in the surfactant's isoelectric range while in others a mineral is floated over a wide range of pH including the mineral's point of zero charge. Electrophoretic mobility studies indicate a positive adsorption of the amphoteric surfactants on these minerals. The adsorption of amphoteric surfactants may be accounted for partially by electrostatic charge attraction but also there should be some special affinity involved between surfactant's polar group and the mineral surfaces. The amphoteric surfactants seem to be potential selective collectors for some oxide minerals.
