Coarse and Fine Particle Flotation Recovery

2016-6-2  Since these sulphides are frequently inter-crystallized to an intimate degree, very fine grinding has to be practiced in many cases. With most of the gold ores which are treated by flotation, the values are distributed among several sulphide telluride minerals. In these cases a collective flotation of the various sulphides has to be made.
