Froth Flotation of Coal Fines at Coal Cliff Colliery

This paper briefly outlines the develop ment of the froth flotation plant at Coal Cliff Colliery. The plant was superimposed onto the original flow sheet in which fines were merely thickened and filtered. Test work leading up to the installation is described and the final layout is discussed. Details of the concentrate and tailings systems are given. Preliminary results of a further extension involving the use of a Davcra flotation machine are also given.
