Coal flotation to satisfy coal quality - ScienceDirect

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.

Coal Flotation Technical Review - ACARP

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 ...

Froth flotation - Wikipedia

The froth flotation process was patented by E. L.Sulman, 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 ...
