Abstract

To improve the separation efficiency of spodumene from gangue minerals, the strengthening of the collection of spodumene and the enlarging of the floatability difference between spodumene and gangue minerals are very important. Spodumene is a silicate mineral with chain structure, and its cleavage planes have obvious anisotropy, which affects the adsorption behavior of collector on each crystal plane. Oleate ions mainly adsorbed on the (110) and (100) planes of spodumene, while the combined collector of oleic acid and dodecyl amine promoted the adsorption of collector on the (001) and (010) planes without reducing the adsorption of collector on the (110) and (100) planes of spodumene, and then it strengthens the flotation collection of spodumene.
