Problems solved by technology

[0004] Because xanthate is combustible, its mineral selectivity is poor, and its storage time is short (generally not more than 80 days), which limits the further application of xanthate to a certain extent.

Embodiment 1

[0018] Xanthate compatibility flotation agent is composed of the following three substances in weight percentage: 80% refined isobutyl xanthate, 15% bistrifluoromethanesulfonimide, and 5% sodium fulvic acid . When using xanthate-compatible flotation agent to float high-sulfur bauxite (aluminum-silicon ratio is 3.23, sulfur content is 2.08wt%), add xanthate-compatible flotation agent to particle size ≤0.074mm to reach 85% (mass percentage) In the bauxite slurry, stirring, adding water to adjust the slurry (pulp concentration 40wt%), scraping flotation, the dosage of flotation agent is 100 g per ton of ore. The specific results are shown in Table 1.

Embodiment 2

[0022] The xanthate compatibility flotation agent is composed of the following three substances in weight percentage: 85% by weight of refined isobutyl xanthate, 10% of bistrifluoromethanesulfonimide, and 5% of sodium fulvic acid. When using xanthate-compatible flotation agent to float high-sulfur bauxite (aluminum-silicon ratio is 3.23, sulfur content is 2.08%), add xanthate-compatible flotation agent to reach 85% (mass percentage) of particle size ≤0.074mm In the bauxite slurry, stirring, adding water to adjust the slurry (slurry concentration 40wt%), scraping flotation, and the dosage of xanthate-compatible flotation agents is 80 g per ton of ore. The specific results are shown in Table 2.

Abstract

The invention discloses a xanthate-compatible flotation reagent and a using method thereof. The xanthate-compatible flotation reagent is prepared from 80-90 wt% of isobutyl xanthate, 8-15 wt% of bistrifluoromethanesulfonimide and 2-5 wt% of fulvic acid sodium. In the using process, the xanthate-compatible flotation reagent is added into ore slurry of which the size fraction is smaller than or equal to 0.074 mm and the mass percent reaches 80% or above, stirring, slurry mixing and bubble scraping and flotation are conducted, and 50 g-100 g of the xanthate-compatible flotation reagent is added into each ton of ore. The xanthate-compatible flotation reagent can serve as a substitute of a traditional xanthate collecting agent in metallic ore flotation, the reagent consumption is reduced, the grade and the recovery rate of useful ore are significantly increased, the sulfur content in oxidized ore is decreased, and remarkable economic and social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a xanthate-compatible flotation agent and a use method thereof. Background technique [0002] Xanthate is the most widely used sulfide ore collector. The annual consumption of various types of xanthate in the world ranges from tens of thousands to nearly 100,000 tons. The commonly used ones are ethyl xanthate, butyl xanthate, isopropyl xanthate, Isobutyl xanthate, amyl xanthate, hexyl xanthate, etc. [0003] Domestically, a lot of research has been carried out on the synthesis, preparation and application of xanthate. For example, Zhong Hong et al. in "A Synthetic Method of Xanthate" (CN 102690218A), designed the reaction raw material ratio as alcohol: carbon disulfide: caustic alkali (sodium hydroxide or potassium hydroxide) = 1: 3~ 9: 1~1.1 (ratio of substance amount), reaction temperature 10 ℃~70 ℃ for 0.5~8 hours of synthesis process, the obtained xan...
