Characterization and Beneficiation Studies of a Low Grade ...

2014-8-19  Total alumina shows strong negative correlation with Fe 2 O 3 because existence of two different phases, alumina mineral (gibbsite and boehmite) and iron minerals (hematite and goethite). The strong positive correlation of total alumina with TiO 2 is due to the presence of significant amounts of titania in the structure of boehmite phase.

Beneficiation of High Silica Bauxite Ores of India an ...

The more is the silica, higher is the soda consumption which increases the cost of alumina production. Physical beneficiation techniques are employed to reduce the reactive silica content of bauxite. Based on several investigations it has been made possible to remove ~30% of silica with 92% recovery depending on the characteristics of the ore.
