A column separation device and method for mineralization-flotation separation

Abstract

A column separation device and method for mineralization-flotation separation, suitable for use in mineral processing technology. Including mixing barrel, pump, bubble generator, mineralization chamber, turbulence elimination pipe, flotation column and air compressor; after the entering flotation pulp is mixed by pulping equipment, it enters the cyclone mineralization chamber after passing through the bubble generator, and rotates at high speed. The high-intensity turbulent collision between the ore pulp and the bubbles occurs to form mineralized bubbles. The mineralized bubbles pass through the turbulence-eliminating tube to eliminate large eddies and then enter the static separation area of ​​the flotation column to complete the static separation. Baffles prevent the slurry from entering the tailings from a short circuit, and the ore particles that have not completed mineralization and desorption are intensively recovered, the low-ash clean coal is recovered, and the high-ash minerals are discharged from the tailings port. It effectively reduces the flotation shedding probability of low-ash and coarse particles, has large equipment processing capacity, strong adaptability to different coal qualities, low production and operation costs, convenient installation and operation, and overall improves the quantity and quality of clean coal products.

Description

technical field [0001] The invention relates to a column separation device and method for mineralization-flotation separation, which is especially suitable for the column separation device and method for mineralization-flotation separation used in mineral processing technology in the field of mineral flotation technology. Background technique [0002] With the increase in the proportion of mechanized coal mining and the decline in the quality of the washed coal, the coal slime has the characteristics of fineness, high ash, and large conjoined body content. The efficiency is difficult to achieve synergy, and the key technologies and equipment for efficient separation of coal slime flotation are urgently needed. With the advancement of coal slime separation technology, new types of equipment continue to appear, but there is still a big gap between its separation effect and efficient separation. As the main sorting equipment for coal slime separation, flotation machine and flo...

AI Technical Summary

Problems solved by technology

For example, the common problems reflected in the sorting of flotation columns in practice are: the processing capacity of the equipment is low; the mineralization efficiency of coarse particles is low, and it is difficult to ensure a low drop-off probability of mineralized bubbles of coarse particles during the flotation process. Due to the short flotation process, its anti-fluctuation ability to different coal quality is weak, these problems are directly reflected in the low ash content of flotation tailing coal, and some low-ash coarse particles are lost in tailing coal
