Flotation Of Fine And Coarse Minerals

Coarse and Fine Particle Flotation Recovery

In this connection it is of particular, practical importance to consider the cases of selective flotation, and of collective flotation as applied to sulphide ores, and to precious metal ores, and to see whether it is possible to apply jointly the advantages of coarse flotation and those of fine flotation for greater operating efficiency.
