The problem of recovering very fine particles in mineral processing …
Abstract. In this review, it is first attempted to put together the available basic knowledge as relevant to the problem of very fine particles, and secondly to analyse the various surface-based methods. The greater part of this vast literature is of a basic, fundamental nature. An acute need to do more research on the problem of very fine ...

New flotation flowsheet for recovering combustible matter from fine
This is because the particles of coal are too coarse or fine to float. Thus, FWCC separation processes will be more efficient when the particle size after grinding and the particle size suitable for flotation match. 5. A flowsheet, including a spiral separator, grinding, and flotation separators, is proposed for the beneficiation of FWCC.
