1.New flotation processes reviewed in this report are highly efficient and available competitively for the Australian Coal Industry With commercial suppliers of new technology already well established, any new research, however prospective the ideas may be, is likely to return little or no benefit to the Industry The study recommends no further research into the process of flotation or in new

2.A process for the flotation of particles of lignitic coal, subbituminous coal or oxidized bituminous coal contained within a slurry of coal and gangue, comprising the steps of dispersing a surfactant throughout the slurry, first conditioning the slurry such that the surfaces of the particles of coal are selectively coated by the surfactant to

3.A reagent and a method for using the reagent are described for treating a solid material disposed in a liquid medium and having an oxygencontrolled surface condition The reagent includes a liquid hydrocarbon, a reducing material and an activator material The liquid hydrocarbon has a specific

5.The Jameson Cell is a highintensity froth flotation cell that was invented by Laureate Professor Graeme Jameson of the University of Newcastle Australia and developed in conjunction with Mount Isa Mines Limited "MIM", a subsidiary of MIM Holdings Limited and now part of

6.The froth flotation process was patented by E LSulman, H F K Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests It was the result of the intelligent recognition of a remarkable phenomenon which occurred while they were experimenting with the Cattermole process This was the beginning When it became clear that froth flotation

7.limiting operation, which enhances the selectivity in the coal flotation process was not considered in the study In fact, the 'columnrelease procedure' was only recommended as an alternative method and was not described as a superior method for characterizing the flotation response of a given material This publication describes the development of a novel flotation characterization procedure

8.Flotation: Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is, the surfaces are either repelled or attracted by water The flotation process was developed

9.During the coal flotation process, high ash coal fines are carried into foam, although process optimization can reduce ash content This paper suggests an alternative method for coal flotation which has a significant effect on quality, coal production processes and plant design
