Problems solved by technology

Although these technical solutions have solved the collection problem of fluorite flotation under the condition of low temperature (10~15℃) to a certain extent, the collection effect is still not very satisfactory, and the recovery rate of fluorite after a rough separation And the grade of the obtained fluorite is not very high; in addition, polyoxyethylene ether carboxylic acid and hexadecyl sulfonic acid and compound oleic acid developed based on oleic acid, sulfated oleic acid and other agents are relatively expensive, so The cost of existing collectors is generally high

[0044] (2) A kind of preparation method of fluorite collector

[0045] Such as figure 1 Shown, a kind of preparation method of fluorite collector, it specifically can comprise the steps:

[0046] Step A, synthesis: select 60-80 parts by weight of unsaturated fatty acid, and add 8-12 parts by weight of sulfonating reagent to carry out sulfonation reaction; after the full reaction is completed, the mixture of unsaturated fatty acid and sulfonated unsaturated fatty acid is obtained mixture.

[0047] Step B, Compounding: Add 5-15 parts by weight of foaming agent, 5-15 parts by weight of diesel oil and 5-10 parts by weight of surface active agent, and after fully stirring uniformly, a compound mixture is obtained.

[0048] Step C, saponification: Fully dissolve 8-12 parts by weight of alkali in water to prepare an alkali solution; uniformly add the alkali solution to the compound mixture obtained in step B, and stir evenly at 30-35°C to make the compound The mixture is fully sa...

Embodiment 1

[0058] Select 72 parts by weight of industrial oleic acid into the reactor, add 8 parts by weight of concentrated sulfuric acid, and stir at 30°C for 1 to 1.5 hours, so that the sulfonation reaction is fully complete, and the reaction solution becomes viscous and gradually colored. get darker. At this time, add 5 parts by weight of MIBC, 10 parts by weight of 0# diesel oil and 5 parts by weight of NP-10 surfactant in the reactor, and fully stir for 1 hour at 30 ° C to obtain a uniformly stirred compound mixture . Dissolve 10 parts by weight of solid sodium hydroxide in 200 parts by weight of water to obtain an aqueous sodium hydroxide solution; slowly add the aqueous sodium hydroxide solution into the reactor, and stir evenly at 30-35°C to fully saponify it, that is A high-selectivity fluorite collector resistant to low temperature is obtained.

[0059] The composition of this fluorite collector can include: the industrial oleic acid of 48 parts by weight, the sulfated oleic...

Embodiment 2

[0067] Choose 72 parts by weight of tall oil and put it into the reactor, and after the temperature is raised to 90°C, add 30 parts by weight of the concentration of 30% sodium bisulfite solution in the reactor, and then keep the temperature at 90°C React for 2 to 3 hours to make the sulfonation reaction fully complete. At this point, add 6 parts by weight of 2# oil, 12 parts by weight of 0# diesel oil and 4 parts by weight of NP-10 surfactant, and fully stir for 1 hour at 50 ° C to obtain a well-stirred complex With the mixture. Dissolve 10 parts by weight of solid sodium hydroxide in 179 parts by weight of water to obtain an aqueous solution of sodium hydroxide; slowly add the aqueous solution of sodium hydroxide to the reactor, and stir evenly at 30-35°C to fully saponify it, that is A high-selectivity fluorite collector resistant to low temperature is obtained.

[0068] The composition of this fluorite collector can include: 42 parts by weight of tall oil, 30 parts by we...

Abstract

The invention discloses a fluorite collecting agent and a preparing method of the fluorite collecting agent. The fluorite collecting agent comprises a main agent, an auxiliary agent, alkali and water, wherein the main agent comprises unsaturated fatty acid and sulfonated unsaturated fatty acid, the auxiliary agent comprises a foaming agent, diesel oil and a surface active agent, the ratio of the total weight of the main agent and the auxiliary agent to the weight of the water is 1:(1-10), and the main agent, the auxiliary agent and the alkali have the following proportion in parts by weight: the unsaturated fatty acid accounts for 40 to 50 parts, the sulfonated unsaturated fatty acid accounts for 25 to 30 parts, the foaming agent accounts for 5 to 15 parts, the diesel oil accounts for 5 to 15 parts, the surface active agent accounts for 5 to 10 parts, and the alkali accounts for 8 to 12 parts. The fluorite collecting agent and the preparing method provided by the embodiment of the invention have the advantages that good low-temperature-resistant selectivity and collecting performance are achieved, stable and excellent flotation effects can be obtained both under the normal-temperature conditions and under the low-temperature conditions, the fluorite recovery rate and the quality of fluorite obtained through flotation are improved, in addition, the preparation process is simple, and the production cost is lower than that of the collecting agent in the prior art, so good market popularization values are realized.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a fluorite collector and a preparation method thereof. Background technique [0002] Fluorite is an important raw material for the fluoride industry, so with the large-scale development of my country's fluoride industry, the demand for fluorite has also risen sharply. my country is rich in fluorspar resources, but the grade of fluorspar is generally low, generally 35-40%, so it needs to be enriched by flotation, so that the grade of fluorspar can meet the requirements of relevant industries and can be used. [0003] For a long time, the flotation process of fluorite has mostly used oleic acid as a collector, soda ash as a regulator, and water glass as an inhibitor, and the flotation process needs to be carried out at room temperature (about 25°C) or heated (30°C above) conditions. However, using oleic acid as a collector has shortcomings such as insufficient collecti...
