Trans. Nonferrous Met. Soc. China 26(2016) 1112-1117 Flotation of low-grade bauxite using organosilicon cationic collector and starch depressant Xin-yang YU1, Hao-lin WANG1, Qiang-qiang WANG1, Bo... and pyrophyllite, using an organosilicon cationic surfactant (TAS101) as collector and starch as depressant was investigated. The results show that both diaspore and aluminosilicate minerals float readily......
