The limits of fine particle flotation - ScienceDirect

Milestones in fine particle flotationIn 1942, research conducted by Gaudin et al. demonstrated that fine particles possess different flotation properties from larger particles. Gaudin proposed that the rate of flotation was independent of particle diameter up to 4 μm, and proportional to the diameter for particles in the range of 4–20 μm.

Introduction to Mineral Processing - Chevron Phillips Chemical

The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.
