Embodiment 5～8

[0021] Examples 5-8 are lead-sulfur mixed tailings with different fineness (that is, different content of less than 0.025 mm), which are used as raw ore for the condition test of this agent, and the process flow is the same as above. Table 2 shows the comparison results of Examples 5-8 using the collector 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%. Ore flotation indicators, and the dosage of chemicals is small.

Abstract

The invention relates to a flotation reagent for improving flotation indexes of sphalerite and belongs to the field of metal mineral beneficiation. The special flotation reagent is prepared by mixing the following solutions by volume percent: 5-20% of a 1-1.5 wt% ammonium dibutyl dithiophosphate solution, 5-15% of a 8-10 wt% sodium(potassium)amyl xanthate solution, 30-40% of a 8-10 wt% sodium O-ethyl dithiocarbonate solution and the balance of a 8-10 wt% sodium n-butyl-xanthate solution. The flotation reagent is high in zinc recovery rate and low in consumption and cost, and has an obvious beneficiation effect on fine sphalerite.

Description

technical field [0001] The invention relates to a flotation agent for improving the flotation index of sphalerite, which belongs to the field of metal ore dressing. 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 has continued to increase, but the flotation indicators have failed. There is a more obvious 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 direction of new agents should be mainly aimed at the problem that xanthate has good collection effect but weak selectivity. Facing the increasingly complex properties of raw ore to be selected, there is a lack of flotation reagents for...
