FLUIDIZED-BED FLOTATION UNIT, MINERAL PROCESSING APPARATUS, AND FLUIDIZED-BED FLOTATION METHOD

摘要

This disclosure relates to a fluidized-bed flotation unit (1000), its use, a mineral processing apparatus, and a fluidized-bed flotation method. The fluidized-bed flotation unit (1000) comprises a tank (1100) for holding a volume of slurry (1001). The tank (1100) comprises a launder (1101) with a launder lip (1102), a fine slurry outlet (1110) below the launder lip (1102), and a coarse slurry outlet (1106) below the fine slurry outlet (1110) for discharging coarse output slurry (1107) from the volume of slurry (1001). The fluidized-bed flotation unit (1100) comprises a solid- liquid separation arrangement (1700) con figured to collect output slurry (1701) from the volume of slurry (1001) via the fine slurry outlet (1110) and to separate suspended solids and flotation liquid from the output slurry (1701) to form a solids portion (1702) and a liquid portion (1703).
