Kaolin Flotation: Beyond the Classical

beneficiation of kaolin entails using methods that are effective in the fine-particle range. It has been observed that certain materials will not float in a froth flotation process when ground to an exceedingly fine size, although they will float under the same conditions when provided in coarser ain size.

US4629556A - Purification of kaolin clay by froth ...

An improved flotation process for removal of colored titaniferous impurities from kaolin clay uses as collector a hydroxamate compound, or a mixture of compounds, having the formula ##STR1## in which R is an alkyl, aryl, or alkylaryl group having 4-28, and preferably 6-24 carbon atoms, and M represents an alkali metal, an alkaline earth metal or hydrogen.

US3827556A - Purification of kaolin clay by froth ...

A method for removing finely divided particles of a colored titaniferous impurity from a dispersed alkaline pulp of kaolin clay by froth flotation. The collector for the impurities is a very low rosin acid tall oil which also provides controlled frothing without the addition of hydrocarbon oils to prevent overfrothing.

Benefication of kaolin clay by froth flotation using ...

Mar 01, 1992  The kaolin clays mined in Georgia contain two major impurities: anatase (TiO 2) and iron oxide. The anatase contains a considerable amount of iron in its lattice, which gives a brownish tint to the clays. This mineral is, therefore, removed by froth flotation to produce coating-grade (bright) clays.

According to Norris and Yordan (9), the C.S. varies from 0.3 to 0.75 in the case of beneficiation of kaolin by froth flotation. The co-collector usage circumvents the use of activators such as the divalent salts normally required with oleic acid (10). This is an interesting phenomenon and merits further investigation.The advantage of prior ...

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. While pure anatase Ti02 is a very white

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.
