Abstract

The invention relates to a mineral flotation device which can generate bubbles by pressing air in and is provided with a ring-shaped combined structure, namely, a ring-shaped pneumatic flotation machine. The pneumatic flotation machine consists of sorting columns, an air pressing type bubble generator, a ring-shaped froth paddle mechanism and a process ore pulp lifting pipe; a plurality of sorting columns are combined to form a ring shape. Ore pulp is fed into a feed port of one sorting column, ore grains subside downwards, while bubbles raise upwards; in this way, the ore grains with hydrophobic property is prepared into rough concentrate through flotation, and then the rough concentrate is sent into fine selection sorting columns for a plurality of times of fine selection to obtain ore concentrate finally. The ore grains with hydrophilicity flow downwards with the ore pulp, pass through the process ore pulp lifting pipe and enter scavenging sorting columns for a plurality of times of scavenging to obtain mine tailing finally. The ring-shaped pneumatic flotation machine of the invention has the advantages of low energy consumption and abrasion, large inflating volume, high probability of collision and attachment between ore grains and bubbles, flexible adjustment of the times and period of fine selection and scavenging and large range of sorting granularity, so as to be an excellent device for mineral flotation, separation and upgrading.

Description

technical field

[0001] The invention relates to the technical field of mineral processing engineering, in particular to an annular air-filled flotation machine, which adopts compressed air to generate air bubbles and has an annular composite structure for mineral flotation. Background technique

[0002] Flotation machine is an important equipment to realize mineral flotation enrichment and separation. The technical and economic indicators of flotation are closely related to the flotation equipment used. There are many types of known flotation equipment, which are mainly divided into mechanical agitation flotation machines, inflatable agitation flotation machines, and inflatable flotation machines. For mechanical agitation flotation machines, the introduction of air is realized by the negative pressure generated by the high-speed rotation of the agitation impeller. When the agitation intensity is low, the generated vacuum is low, the amount of air introduced is insufficient,...
