Problems solved by technology

[0004] At present, the ore dressing of coarse-grained wolframite is generally recovered by gravity separation at home and abroad, and the recovery rate of wolframite is mostly below 45%, and the loss rate is relatively large; for fine-grained wolframite, especially fine-grained wolframite At present, wolframite ore is mainly recovered by gravity separation, gravity-flotation combined process and other methods at home and abroad. However, due to the complicated process or the low selectivity of flotation reagents, no better recovery method has been found so far.

Embodiment 1

[0017] An example of the preparation method of wolframite collector of the present invention, comprises the following steps:

[0018] First, oleic acid and sodium methanesulfonate were stirred and mixed at room temperature for 1 hour at a mass ratio of 1:1 to obtain solution 1, and then ethylenediamine was slowly added to solution 1 at a mass ratio of 1:3. Stirring and reacting at ℃ for 2.5 hours to prepare solution 2, and finally neutralizing with 10% sodium hydroxide, the obtained brownish-yellow translucent thick substance is the wolframite collector.

Embodiment 2

[0020] Another example of the preparation method of wolframite collector of the present invention, comprises the following steps:

[0021] First, oleic acid and sodium methanesulfonate were stirred and mixed at room temperature for 1 hour at a mass ratio of 2:3 to obtain solution 1, and then ethylenediamine was slowly added to solution 1 at a mass ratio of 2:7, at a temperature of 90°C The solution 2 was prepared by stirring and reacting under the conditions for 3 hours, and finally neutralized with 15% sodium hydroxide, and the obtained brownish-yellow translucent thick substance was the wolframite collector.

Embodiment 3

[0023] This embodiment is an application example of the wolframite collector in flotation wolframite.

[0024] 1. Mineral raw materials:

[0025] The tungsten content in the ore used is 0.37%, the silicon dioxide content is 13.54%, and the iron content is 15.75%. Phase analysis shows that tungsten mainly exists in the form of wolframite, and there is a small amount of scheelite; the gangue minerals are mainly silicon It exists in the form of acid salt, and some magnetite and goethite.

[0026] 2. Flotation agents and operating conditions:

[0027]

[0028] During the flotation process, after the ore is ground until the mineral monomers are dissociated, sodium carbonate and water glass are added to disperse and suppress the gangue minerals, then lead nitrate is added to activate wolframite, and finally the collector is added to the wolframite Collect tungsten concentrate products. The test results show that wolframite can be effectively recovered by adopting the above pro...

Abstract

The invention discloses a preparation method of a wolframite collecting agent. The preparation method comprises the following steps of firstly, stirring and mixing oleic acid and sodium methanesulfonate for one hour at the normal temperature according to the mass ratio of (1-2): (1-3), so that a solution 1 is obtained; then, slowly adding ethylenediamine to the solution 1 according to the mass ratio of (1-2): (3-7), and stirring the mixture and making the mixture react for 2.5-3 hours at the temperature of 85-90 DEG C, so that a solution 2 is obtained; and finally, adding sodium hydroxide with the mass percentage concentration ranging from 10% to 15% for neutralization, so that claybank semitransparent thick matter is obtained, wherein the claybank semitransparent thick matter is the wolframite collecting agent.

Description

[0001] 1. Technical field [0002] The invention relates to a preparation method of a wolframite collector, in particular to a preparation method of a microfine wolframite collector. [0003] 2. Background technology [0004] At present, the ore dressing of coarse-grained wolframite is generally recovered by gravity separation at home and abroad, and the recovery rate of wolframite is mostly below 45%, and the loss rate is relatively large; for fine-grained wolframite, especially fine-grained wolframite At present, wolframite ore is mainly recovered by gravity separation, gravity-flotation combined process and other methods at home and abroad. However, due to the complicated process or the low selectivity of flotation reagents, no better recovery method has been found so far. . For wolframite with fine particle size, low grade, and gangue minerals containing a large amount of quartz and fine mud, the value of fine-grained wolframite lost in the tailings every year is tens of b...
