Practical Optimisation of the Flotation Circuit at West Cliff Washery

The beneficiation of fine coal has been the major problem facing the coal preparation engineer in recent years. The influence of clay slime, particle size and reagent type are but a few of the many factors that affect the recovery of fine coal. Laboratory test work has indicated that substantial increases in recovery could be achieved by improvements in technology in all these areas. Unfortunately, in most cases this technology has not carried through to the operating plants.
