Because flotation is partially dependent on ore particle size, regrinding of the particles between the rougher and cleaner flotation cells may be needed. Tailings from the cleaner flotation may be sent back to the flotation circuit for additional recovery (Biswas and Davenport 1976; U.S. DOI, Bureau of Mines 1965a; Wills 1981).
