Abstract

The invention discloses a columnar flotation device. The columnar flotation device comprises a flotation column columnar shell, a concentrate overflow trough located on the outer side of the upper portion of the shell, air pipes located at the inner bottom of the flotation column shell and a pulp feeder located on the inner upper portion of a flotation column. The pulp feeder is connected with a mineral feeding pipeline, and a tailing discharging opening is arranged in the middle of the flotation column shell. The shell is further provided with a concentrate discharging opening, and the position of the concentrate discharging opening is higher than that of the tailing discharging opening. The lower portion of the shell is of a cone structure, an accident emergency gate valve opening is mounted at the bottom of the cone structure, and the tailing discharging opening and the accident emergency gate valve opening are both provided with valves for control. The columnar flotation device ishigh in flotation pulp flow speed, large in collision probability with bubbles, high in turbulent degree, good in mineralization effect, capable of recycling micro-fine particle minerals well and meeting the requirement of the micro-fine particle mineral separation process and wide in application range.

Description

technical field

[0001] The invention relates to a column type flotation device for microfine minerals, in particular to a column type device for the flotation process of microfine minerals. Background technique

[0002] Flotation technology is an economical and effective sorting method in the field of mining to enrich useful minerals that can reach the standard metal content for smelting from natural primary ores. The selected equipment mainly includes mechanical agitation flotation machines and non-mechanical agitation flotation machines.

[0003] The development of mechanical agitation flotation machines has a history of many years at home and abroad, and the technology is becoming more and more mature. However, this type of equipment has unavoidable shortcomings. Due to high energy consumption and strong interference in the mechanical stirring area, the fine mineral particles carried by the air bubbles after mineralization are easily affected by it and fall off, resultin...
