Diasporic-bauxite flotation in China is used as an example to describe the flotation process. This flotation is a direct flotation process that achieves flotation froth as the concentrate and underflow as the tailings. The diaspor ic-bauxite is characterized by a high content of Al 2 O 3 and SiO 2 and a low ratio of Al 2 O 3 and SiO 2 (m (Al 2 O 3)/m (SiO 2) =A/S, usually between 5 and 6).
