Title:
COLUMN SORTING APPARATUS AND METHOD FOR MINERALIZATION-FLOATATION SEPARATION
Document Type and Number:
WIPO Patent Application WO/2020/155421
Kind Code:
A1
Abstract:
A column sorting apparatus and method for mineralization-floatation separation, comprising a stirring vessel (1), a pump (2), a bubble generator (3), a mineralization chamber (6), a turbulence removal pipe (8), a flotation column (11), and an air compressor (17). After being mixed by a pulp conditioning equipment, flotation pulp passes through the bubble generator (3) and then enters the mineralization chamber (6). The pulp rotating at a high speed and bubbles carry out a high-intensity turbulent collision and form mineralization bubbles. Big vortexes of the mineralization bubbles are removed by the turbulence removal pipe (8) and then the mineralization bubbles enter a static sorting area of the flotation column (11) to complete static separation. A flotation assist baffle plate (13) is provided at the bottom of the static sorting area of the flotation column (11). Enhanced recovery is performed on mineral particles on which mineralization and desorption are not completed, low-ash coal concentrate is recovered, and a high-ash mineral is discharged from a tailing port (14).
