Kaolin Flotation: Beyond the Classical

Carrier mineral flotation or [ultraflotation" was the first successful anatase-removal pro- cess used with kaolin on a large scale at Engelhard Corporation and was put into commer- cial operation in 1961 (Greene et al., 1961). In this process the conditioning of kaolin is

PRE-CONCENTRATION AND FLOTATION OF ALUNITIC

milling time for the kaolin was found to be 120 min. Consequently, raw kaolin samples were ground in the ball mill for 120 min and then passed through a 38 µm screen. The kaolin was then dewatered and dried at 100 °C before they were stockpiled for flotation tests. The kaolin samples prepared by this method were coded as NS.

Kaolin Wet-Processing Helals

The simplest process is called air flotation or the dry process. The properties of the finished product depend to a large extent on those properties inherent in the crude kaolin. In the dry process operation, a deposit must be chosen with desirable properties of color and relatively low content of grit ( > 44 µ).

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.
