The limits of fine particle flotation ScienceDirect

Understanding the limits of fine particle flotation is the key to the selective separation of fine mineral particles. Fine particles have low collision efficiencies with gas bubbles and float slowly. However, in the minerals processing industry, selectivity is essential. Electrolyte addition often causes heterocoagulation, however it is
