Coarse and Fine Particle Flotation Recovery

 · This technical objection has an economic corollary; finer gold flotation means higher power cost for flotation and decreased cell capacity. In the third place, fine particles of gangue are more likely to overflow mechanically in the pulp carried over between bubbles, so that a high-grade concentrate is more difficult to obtain, and more cleaning operations may be required if a fine ground pulp is treated.
