Title:
FLOW SYNERGY-ENHANCED FLOTATION SEPARATION APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/220584
Kind Code:
A1
Abstract:
A flow synergy-enhanced flotation separation apparatus and a method, suitable for use in flotation of microscopic mineral particles or coal particles. The apparatus comprises a circulation pump (1), a mineralization turbulent flow generator (2), and a flotation separation releaser (5). A pulp is fed into the flotation separation releaser (5), and more-buoyant particles rapidly rise and are expelled by means of a concentrate pipe (16) on a froth trough (3) above the flotation separation releaser (5). Moderately-buoyant particles are separated by means of the flotation separation releaser (5), and then a portion float to the froth trough (3) above the flotation separation releaser (5) and are expelled via the concentrate pipe (16) on the froth trough (3). Less-buoyant particles that have been separated by the flotation separation releaser (5) enter a middling/tailing separator via a pulp flow channel between a conical flow director and a cylindrical wall of the flotation separation releaser (5), and are divided into two portions. One portion serves as tailings and is expelled from the flotation separation releaser (5), and a portion is fed into the mineralization turbulent flow generator (2) by means of the circulation pump (1), and after undergoing high-efficiency mineralization, is sprayed back into the flotation separation releaser (5), thus achieving circulating separation. The invention features a simple structure and an excellent flotation result.
