Minerals or metals are separated from a mixture of crushed ore, aq. soln., and flotation agent by passing the mixture from an inlet through free fall into a container to entrap air during the free fall and is encourage the development of a large quantity of froth. - Used in cascade flotation process for recovery of minerals or metals from ore. The separator unit can float much coarser materials and heavier minerals which leads to increased recoveries of heavier precious metals such as Au, Ag and faster recoveries of base metals still in a coarse state. The ability of the unit to separate coarse material reduces necessity for excessive fine grinding of ores to attain max. mineral recovery. (Provisional Basic previously advised in Week K09) |
