Abstract Results of the beneficiation of the diaspore-kaolinite-bearing bauxite by flota-tion, from laboratory and small-scale continuous processing to pilot plant testingare described. Using raw materials with initial Al_2O_3/SiO_2 ratio of 4.6-5, theflotation concentrates finally attained a ratio greater than 8 with a recovery of Al_2O_3amounting to 70-80%. Results of digesting test for producing alumina by Bayer process, as well astests for making comprehensive utilization of the flotation tailings are also presen-ted.
