07/02/2013· Flotation methods include ore flotation, macro flotation, colloidal flotation, ion flotation and precipitate flotation. Precipitate and adsorbing colloid flotation are processes that, together with ion flotation, possess some advantages for treating large volumes of wastewater solutions. Precipitate flotation requires precipitation of the metal species in preparation for subsequent flotation

01/01/1987· Ore flotation, certainly, has been well established for many years and will presumably continue to be of great importance. As we exhaust our reserves of me tal ores, the recovery of metals from ores of progressively lower grade is neces sary and ion flotationes advantageous in dilute solutions, resulting from hydrometallurgical processes.
