Preparation method and device for fluorite mine floatation efficient inhibitor

Abstract

The invention discloses a preparation method and a device for a fluorite mine floatation efficient inhibitor. The method and the device are used for flotation separation of fluorite minerals, carbonate gangue minerals and silicate gangue minerals particularly. A water glass medicine inlet (2) and an acid or salt medicine inlet (1) are arranged on the upper portion of a mixing cavity (3), a water inlet (7) is arranged at the bottom of the mixing cavity (3), the upper outlet of the mixing cavity (3) is in butt joint with the upper portion of a buffering cavity (4), the upper outlet of the buffering cavity (4) is in butt joint with the upper portion of an overflowing cavity (5), and a medicine outlet (6) is arranged at the bottom of the overflowing cavity (5). Water glass, water and acid (such as sulphuric acid and chlorhydric acid) or salt (such as aluminum sulphate and ferrous sulphate) are mixed in the mixing cavity, enter the buffering cavity and are subjected to the reaction, and a finished product is formed, flowed out and used through the overflowing cavity. By the aid of the device, the inhibitor can be used immediately after being prepared and has efficient inhibiting effect. The effect is good, the operation is simple and the use is convenient.

Description

technical field [0001] The invention relates to a configuration method of high-efficiency inhibitors for fluorite ore flotation, especially for flotation separation of fluorite minerals and gangue minerals of carbonates and silicates, and also relates to a device for realizing the method. Background technique [0002] Fluorite is an important auxiliary raw material in the metallurgical industry, and an important raw material for the production of hydrofluoric acid and fluoride in the chemical industry. my country's fluorite ore resources are very rich, and with the development and utilization of mineral resources in our country is getting higher and higher, fluorite ore resources are poor, and there are more and more hybrid phenomena. At the same time, the quality requirements for fluorite mineral products are increasing, so Impurity removal is the main purpose of fluorite ore beneficiation. At present, flotation is generally used to remove impurities to obtain high-grade fl...

Problems solved by technology

However, acidified water glass or salted water glass all add electrolytes to the water glass solution to form a silicic acid colloidal solution to increase the inhibitory effect of the water glass, but this colloidal solution is very unstable and easily forms gel precipitation. lost effect
