Kaolin Flotation - ScienceDirect

Dec 01, 2002  Kaolin is valued as a white pigment and therefore the goal in kaolin flotation circuits is to remove the colored impurities to result in an acceptable brightness product. Kaolin flotation originated with a novel carrier flotation process and later on carrierless flotation techniques were developed.

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.

Sep 01, 1991  In this technique, the crude clay after degritting through 325 mesh screen and dispersion with sodium silicate (3.5 lb/T) was conditioned with ammonium sulfate (6 lb/T) and carrier particles ( -325 mesh calcite). The carrier min- eral particles pick up the micron sized anatase particles and are separated from the kaolin in the flotation process.

Carrier flotation of alunite from kaolin clay - ScienceDirect

Jan 01, 2000  A kaolin sample with high SO 3 content, obtained from the Balıkesir-Sındırgı region, was used to study separation of alunite from kaolin by carrier flotation. Several parameters believed to be effective on separation were tested. Collector amount, pulp pH, size and amount of carrier mineral, agitation time and speed, and pulp temperature were varied and separation conditions were optimized.
