The Removal Of Mineral Impurities From Kaolin Using …

Generally, flotation processes remove Ti02 from the kaolin which improves product brightness. Iron content is not much affected by flotation. Unlike many flotation processes where the desired component is concentrated in the froth, kaolin flotation is the reverse of this, i. e., the undesired component is removed in the froth and discarded.

The Influence of Froth Height in Column Flotation of ...

In froth flotation, the froth height, the entrainment and the drainage of particles affects recovery and grade. The aim of the froth phase is to transport all the hydrophobic particles that reach the pulp/froth interface into the floated and the drainage of the hydrophilic particles into the pulp. In this study, the influence of the froth height in the reverse flotation of kaolinitic ore was ...
