Significance of particle aggregation in the reverse

Jul 01, 2015· An important result of recent bauxite flotation research was the opening in 2002 of the first bauxite mineral processing plant in China (and in the world) which uses direct flotation to prepare a bauxite concentrate for the Bayer process (Zhao et al., 2010). One million tons/yr of bauxite ore can be treated at this plant.

The Influence of Backwater Al3+ on Diaspore Bauxite Flotation

The effect of Al3+ in backwater on the flotation of diaspore bauxite was investigated by micro-flotation tests and the underlying mechanisms were investigated by inductively coupled plasma (ICP) measurement, zeta potential measurements, solution chemistry analyses, and synchrotron near edge X-ray absorption fine structure (NEXAFS) analyses. The ICP measurement results show the
