Abstract
An apparatus and a method for concentrating an ore to recover valuable minerals from the ore is disclosed. The apparatus is based upon flotation separation techniques and comprises a trough into which is fed a slurry of ore particles which have been conditioned with a flotation reagent. The trough has a side extending outwardly forming a downwardly sloping flat table. The slurry of conditioned ore particles flows out of the trough and downwardly along the sloping table. Positioned along the sloping table is a disperser for dispersing larger particles up and into the slurry, which larger particles are generally along the surface of the sloping table. The sloping table is equipped with at least one aerator positioned along the flow path of the slurry, downstream of the disperser which aerates the conditioned ore slurry. The particles coated with the flotation reagent form agglomerates with gas bubbles produced by the aerator. These agglomerates float at a higher level within the slurry than the non-coated, non-agglomerating ore particles. A splitter is positioned near an open end of the sloping table. The splitter height above the surface of the sloping table is adjustable for intersecting the conditioned ore slurry at differing levels. The splitter separates the agglomerative, coated particles floating at a higher level from the non-agglomerative, non-coated particles floating at a lower level in the slurry.
