Abstract

The invention belongs to the technical field of mineral flotation, and concretely relates to a fluorite flotation collector, and a preparation method and an application thereof. The flotation collector includes dioctyl sulfosuccinate sodium salt, oleic acid and ethanol. The flotation collector has the advantages of strong collection ability, good water-soluble dispersibility, good flotation selectivity and stable flotation index, can improve the recovery rate of fluorite flotation, and has a good repetition effect in large-scale industrial applications. Concentrate obtained by flotation usingthe collector has a high recovery rate and a low silica content, and the grade of tailings is low. Additionally, the flotation collector also can be used to float minerals at a low temperature, can effectively avoid problems such as slurry heating, and is conducive to energy saving and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of mineral flotation, and in particular relates to a fluorite flotation collector and its preparation method and application. Background technique [0002] The flotation method is a mineral processing method that selectively separates minerals based on the differences in surface physical and chemical properties. It is characterized by the selective adsorption of collectors on the surface of useful minerals, so that it selectively attaches to the air bubbles in the pulp. Then it floats up to the surface of the slurry to separate the useful minerals from the gangue. Taking fluorite as an example, as the grade of fluorite raw ore becomes lower and the intercalation of fluorite and gangue minerals becomes closer and closer, only through fine grinding can the dissociation of fluorite mineral monomers be achieved. The most effective method for the separation of fine-grained ores is flotation. [0003] Chinese pa...
