Separation of silica from bauxite via froth flotation

Bauxite Beneficiation by flotation method - Crushers, Ball

The main component of bauxite is alumina. Bauxite beneficiation by flotation process can be roughly divided into washing – primary beneficiation – crushing – grinding – classification – separation – concentrate concentration–filtration,several processes.

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

The open-circuit flotation results also show that a bauxite concentrate with m(Al 2 O 3)/m(SiO 2) over 9.3 and Al 2 O 3 recovery over 76% can be obtained from diasporic-bauxite ore. The result of XRD of the bauxite concentrate shows that pyrophyllite is easier to be removed from diasporic-bauxite than illite and kaolinite due to its better
