The conventional process of bauxite ore dressing consists on the removal of natural mud through the steps of crushing, semi-autogenous grinding, crumble in trommel, followed by the removal of the fine fraction (-37 µm) by screening or classification in hydrocyclone and thickening [1, 2], though this process does not remove all the reactive silica.

 · It contains 1-3% calcite. The calcite has a crush strength much lower than the silica and is therefore not desired. The sand size range is 0.1 mm to 1.00 mm. The calcite is uniformly distributed, size wise, in the silica. What are the best ways to remove the calcite on a large scale without impacting the silica?
