preparation example Construction

[0024] The preparation method of the medicament is to prepare the above-mentioned four kinds of raw materials into corresponding concentrations according to the content of the above-mentioned formula, and then mix them according to a certain ratio.

[0025] The use method of the medicament is the solution prepared in the above manner, and the prepared medicament is directly added for the roughing operation in the sphalerite flotation operation.

[0026]

[0027] Prepare the medicament according to the preparation method in the above table, wherein: 1 part of sodium ethyl xanthate; 1 part of sodium butyl xanthate; 1 part of sodium amyl xanthate; 1 part of dibutyl ammonium dithiophosphate. The above 4 kinds of raw materials are prepared into corresponding concentrations and mixed according to the proportion.

[0028] The method of using the medicament is the solution prepared in the above way, and the prepared medicament can be directly added to the sphalerite roughing operat...

Embodiment 1-4

[0030] Examples 1-4 are tailings after mixed separation of lead and sulfur, and the grades of sphalerite in the zinc separation process are not the same.

[0031] The example 1-4 technological process and condition of adopting collector of the present invention and conventional medicament see respectively figure 1 and figure 2 , embodiment 1-4 result comparison is shown in Table 1. It can be seen that, compared with conventional medicament conditions, its sphalerite recovery rate of the new medicament condition test of the present invention improves respectively by 2.57%, 1.49%, 2.31%, 2.21%, and the new medicament of the present invention can significantly improve sphalerite floating rate. The index is selected, and the dosage of medicine is small.

Embodiment 5~8

[0035] Examples 5-8 are lead-sulphur mixed tailings with different fineness (that is, different content less than 0.025 mm), which are used as raw ore for the condition test of the new agent, and the process flow is the same as above. Table 2 shows the comparison results of examples 5-8 using collectors of the present invention and conventional agents. It can be seen that, compared with conventional medicament conditions, its sphalerite recovery rate of the new medicament condition test of the present invention improves respectively by 1.15%, 2.71%, 2.69%, 2.80%, and the new medicament of the present invention can improve fine-grained sphalerite Ore flotation indicators, and the dosage of chemicals is small.

Abstract

The invention discloses an efficient flotation reagent for fine-grained sphalerite separation, a preparation method and application thereof. The efficient flotation reagent for fine-grained sphaleriteseparation is composed of a sodium ethyl-xanthate solution, a sodium butyl xanthate solution, a sodium amyl xanthate solution and an ammonium dibutyl dithiophosphate solution. The preparation methodincludes: mixing the raw materials according to the formula ratio uniformly to obtain the target object efficient flotation reagent for fine-grained sphalerite separation. The efficient flotation reagent for fine-grained sphalerite separation can be applied to a complex sulfide ore separation process. The prepared reagent can be directly added for roughing operation in sphalerite flotation. The method and the collecting agent provided by the invention have obvious technical index advantages, economic benefit advantages and environmental advantages when applied to flotation process.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metals, and in particular relates to a high-efficiency flotation agent for fine-grained sphalerite separation and its preparation method and application. Background technique [0002] The separation of complex sulfide ores is a major problem in the flotation process of non-ferrous metals in my country. With the depletion of resources, the amount of chemicals consumed for poor, fine, miscellaneous, and difficult-to-select ores continues to increase, but the flotation indicators have not been compared. Visible improvement. Xanthate has been used as a sphalerite collector in China. Although it can achieve better results to a certain extent, its selectivity for fine-grained sphalerite is slightly insufficient. The development of new agents is mainly aimed at the problem that xanthate has good collection effect but weak selectivity. Facing the increasingly complex properties of raw ore to be selec...
