Title:
NANOBUBBLE FLOTATION COLUMN
Document Type and Number:
WIPO Patent Application WO/2021/120370
Kind Code:
A1
Abstract:
A nanobubble flotation column, consisting of a slurry pump (1), a swirl injection nano cavitation bubble nozzle (2), an ore slurry distributor (3), a plurality of swirl injection nozzles (4), a flotation column group, and a plurality of transport pipes (9). The slurry pump (1), the swirl injection nano cavitation bubble nozzle (2), and the swirl injection nozzles (4) produce nanobubbles or local disturbance in a flowing ore slurry to produce nanobubbles to activate flotation. The application of the invention in mineral flotation can increase the recovery rate of minerals and also reduce the amount of chemicals and energy consumption, improve the quality and efficiency, and achieve large-scale flotation equipment and intelligent industrial production.
