1 The carrier flotation process makes it possible to select fine grained kaolin. The advantage is that the kinetic energy of the particles is increased, but the consumption of the agent is high, and the use and processing cost of the carrier mineral is further increased.
Kaolin formed by deep weathering of a 30 m thick quartzbiotite schist unit at the top of the Adelaidean Saddleworth Formation. The bulk of the ore is pale yellow to white sandy kaolin used in general cement manufacture. High grade zones comprise masses of almost pure kaolin up to 50 m wide, 30 m deep and 100 m long.

several years. There are no general flotation methods that have been developed for ben eficiation of fine particles. ach industry has developed its own way of dealing with the problem of flotation of fine particles. In this section the different flotation processes used for beneficiation of kaolin are described in a chronological order.
Dilution water is added to each stage of flotation to maintain dilute pulp conditions. The rougher tailings and reflotation tailings are combined and scavenged of any additional contaminant in a 4 cell Sub A Flotation Machine. The tailings from this final flotation step represents the beneficiated kaolin and is pumped to a thickener.
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.
