flotation to remove iron from kaolin

The Removal Of Mineral Impurities From Kaolin Using Flotation

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.

Reduction of Titanoferrous Impurities from Kaolin by

free iron from Kerala kaolin is removed by CDB treatment whereas in Gujarat kaolin both free and structural iron associated with titanoferrous impurity was difficult to remove. The crude kaolin contained 1.63 and 0.66 % TiO2 in Kerala and Gujarat kaolin respectively. Reduction of TiO2 in case of Gujarat kaolin was from 1.63 to 0.99%.
