Central circulation flow guide type rotational flow inflatable flotation equipment and method thereof

Abstract

The invention relates to a central circulation flow guide type rotational flow inflatable flotation equipment and a method thereof. The equipment comprises a middling feeding circulating pipe, a flotation column body and a circulating pump, a flow guide disc is arranged in the flotation column body, the upper end of the flow guide disc is connected with a central flow guide pipe, the central flowguide pipe extends out of the top of the flotation column body, a middling bottom cone and an underflow bottom cone are arranged at the bottom of the flotation column body, the middling bottom cone isconnected with a circulating feeding barrel through a pipeline, a middling valve is arranged on the pipeline, and an outlet of the underflow bottom cone is connected with an underflow pipe and provided with an underflow control valve; an inlet of the circulating pump is connected with the circulating feeding barrel, an outlet of the circulating pump is connected with the middling feeding circulating pipe, the middling feeding circulating pipe is connected with the central flow guide pipe, and closed circulation of middling pulp is formed. The central flow guide disc is arranged in the middleof the flotation column body, liquid-solid-gas mixed circulating middling is introduced into the flotation column body to form rotational flow, and the product has the advantages of being good in amplification adaptability and good in selectivity.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of mineral resources, and in particular relates to a central circulation diversion type cyclone inflatable flotation column equipment and a sorting method. Background technique [0002] In the field of resource recovery and mineral processing, flotation achieves separation by virtue of the difference in surface and interface properties between mineral particles. The mineral flotation process is based on the differences in the surface physical and chemical properties of mineral particles, and uses the buoyancy of air bubbles in the slurry to achieve mineral separation. With the help of air and foaming agent to generate fine bubbles in water, hydrophobic minerals can adhere to the bubbles, and float together with the bubbles to the foam layer, and then be discharged as foam products (concentrate during positive flotation). Hydrophilic minerals or mineral particles with poor hydrop...

AI Technical Summary

Problems solved by technology

To a certain extent, there are certain problems after the diameter of the flotation column is enlarged, and the flotation index and flotation efficiency are attenuated.
