Abstract. The low-grade bauxite, which is abundant in China, cannot be directly used in Bayer process. Flotation of low-grade bauxite is an effective way to improve the grade. Flotation experiments were carried out by using modified humics as depressant in this paper. The effects of pulp pH, collector dosage and depressant dosage were examined.
