Abstract

The invention relates to a single-trough floatation method adopting a helical rotor, a device and a use, pulp to be floated is fully contained in a trough cavity of a single-trough floatation device, and the pulp flows into a flotation startup device via an annular inlet at the bottom of a cavity of the helical rotor. The pulp to be floated comprises ore pulp and tailing pulp generated by at least one stage of flotation process. The expanded area of the annular inlet comprises the cross section area which is equal to or larger than or smaller than the cavity of the helical rotor. The flotation startup device is the cavity containing the helical rotor and comprises the cavity of the helical rotor, the helical rotor, a rotor scraping plate, a dispersion impeller, a squirrel cage type statorand a rotor top cover, wherein the helical rotor can generate at least one helical gas field during rotation. The single-trough floatation method adopting the helical rotor and the device can be usedin the laboratory flotation process and the industrial flotation process, which are applied in all minerals.

Description

Technical field [0001] The invention relates to a flotation method and device, in particular to a single-slot flotation method and device using a helical rotor, belonging to the technical field of flotation. Background technique [0002] "Flotation Method and Device Using Spiral Rotor" (CN201010129013.0), through the invention of the hollow spiral rotor, realizes N (N>1) times of gas-liquid mixing of the pulp to be flotation in the floating device in an irreversible flow mode The flotation process greatly improves the flotation efficiency. However, when it is used as a single-tank flotation device, since the ore pulp cannot effectively flow back to the flotation device after flotation, the multi-stage flotation process in the same tank cannot be implemented efficiently, thus limiting the wide application of the flotation method and device using the screw rotor application, especially limits the application of the method and device as a laboratory research tool. Therefor...
