Embodiment 1

[0041] According to the mass ratio of 1:340, sodium hydroxide and water were respectively taken to form a sodium hydroxide solution, and steam was introduced to raise the temperature of the sodium hydroxide solution to 100°C, and 1 kg of sodium hydroxide solution was added to 53 kg of sodium hydroxide solution. The ratio of oleic acid is to add oleic acid to the sodium hydroxide solution after heating, and stir for 30 minutes to make the reaction fully proceed. During the process of adding oleic acid to the sodium hydroxide solution and stirring, continue to feed steam to keep the reaction temperature constant. Keep it at 100°C. After the heating reaction is completed, stop adding steam and let it stand for 30 minutes to remove other fatty acid reactants with higher melting points floating on the upper part of the reacted liquid, and cool the reacted liquid to room temperature to obtain modified oleic acid; According to the mass ratio of 1:3, the density is 1.46g / cm 3 Add sodi...

Embodiment 2

[0052] According to the mass ratio of 1:350, sodium hydroxide and water were respectively taken to form a sodium hydroxide solution, and steam was introduced to raise the temperature of the sodium hydroxide solution to 90°C, and 1 kg of sodium hydroxide solution was added to 53 kg of sodium hydroxide solution. The ratio of oleic acid is to add oleic acid to the sodium hydroxide solution after heating, and stir for 35 minutes to make the reaction fully proceed. During the process of adding oleic acid to the sodium hydroxide solution and stirring, continue to feed steam to keep the reaction temperature constant. Keep it at 90°C. After the heating reaction is completed, stop steaming and let it stand for 40 minutes to remove other fatty acid reactants with higher melting points floating on the upper part of the reacted liquid. Cool the reacted liquid to room temperature to obtain modified oleic acid. ;According to the mass ratio of 1:3.5, the density is 1.46g / cm 3 Add sodium wate...

Embodiment 3

[0058] According to the mass ratio of 1:345, sodium hydroxide and water were respectively taken to form a sodium hydroxide solution, and steam was introduced to raise the temperature of the sodium hydroxide solution to 95°C, and 1 kg of sodium hydroxide solution was added to 53 kg of sodium hydroxide solution. The ratio of oleic acid is to add oleic acid to the sodium hydroxide solution after heating, and stir for 32 minutes to make the reaction fully proceed. During the process of adding oleic acid to the sodium hydroxide solution and stirring, continue to feed steam to keep the reaction temperature constant. Keep it at 95°C. After the heating reaction is completed, stop steaming and let it stand for 50 minutes to remove other fatty acid reactants with higher melting points floating on the upper part of the reacted liquid. Cool the reacted liquid to room temperature to obtain modified oleic acid. ;According to the mass ratio of 1:3.25, the density is 1.46g / cm 3 The sodium wat...

Abstract

The invention relates to a mineral separation process, in particular to a mineral separation process of complex fluorite difficult to separate. The process includes utilizing sodium hydroxide to treat oleic acid to obtain modified oleic acid, utilizing concentrated sulfuric acid to treat water glass and obtain acidized water glass, conducting ore grinding on fluorite ores according to the prior art, conducting coarse separation under the temperature of 25-30 DEG C, then conducting seven times fine separation on coarse separation foams and adding the acidized water glass into the foams in the first four times of fine separation to prepare fluorite concentrate. The process can improve separation efficiency of calcium fluoride, silica and calcite, improves quality and recycle rate of the fluorite ores, obtains high quality acid grade fluorite ores and resolves the problem of difficulty in separation of complex fluorite flotation, is remarkable in application effect in separation of the complex fluorite difficult to separate, has repeatability, simultaneously reduces requirements of fluorite mineral flotation for ore temperature, reduces energy consumption, reduces usage of collectingagent oleic acid, reduces environment pollution caused by exhaust of a large amount of waste water containing oleic acid and has better economical and social benefits.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and relates to a fluorite ore beneficiation process, in particular to a complex refractory fluorite ore beneficiation process. Background technique [0002] Fluorite is the main raw material for the production of fluorine-containing compounds, and because of its low melting point, it is widely used in steelmaking, non-ferrous metal smelting, cement, glass, ceramics and other industries. Colorless and transparent large fluorite crystals can also be used as optical fluorite and Craft fluorite. With the rapid development of the global market economy, especially the rapid development of my country's non-ferrous metallurgy industry, the demand for acid grade fluorspar concentrate is increasing day by day, thus accelerating the progress of new technology for fluorspar mineral processing. The composition of complex fluorite ores is relatively complex, and it is difficult to separate fluorite...
