Kaolin Flotation - ScienceDirect
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.

Influence of Froth Height on Column Flotation of Kaolin Ore
Batch flotation tests were carried out in a column flotation, for mineral processing of kaolin by reverse froth flotation, in order to float quartz, goethite, ilmenite, rutile and tourmaline, the main penalty minerals of kaolin. In this case, the floated product concentrates the impurities and the tailings (sunk) is the improved kaolin.

Kaolin Processing Technology and Characteristics ...
A clay development company uses carrier-free flotation technology to remove iron from kaolin by flotation. During the flotation process, Ca2+ is added to activate the flotation process, and at the same time, high-strength scrubbing of the kaolin slurry is carried out to remove surface contaminants. A good flotation effect has been achieved.

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.

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.

Removal of fine quartz from coal-series kaolin by flotation
Flotation tests were undertaken on both pure kaolin and quartz. All flotation tests were conducted in a 1.5 L mechanical laboratory flotation machine operating with an air flowrate of 4.5 L/min.The mass of solid particles used in each test was 30 g for both kaolin and quartz.These flotation tests were conducted in accordance with the flowsheet shown in Fig. 1.

The purpose of the flotation operation is to float titanium impurities from the kaolin. Since the impurity particles are extremely fine, a carrier flotation process is usually employed. The carrier mineral may be calcite or silica sand (-325 mesh), and the amount of the carrier mineral is generally 10% to 20% by weight of the kaolin, and a part ...
