Efficient collecting agent applied to low-grade copper-nickel sulfide ore and preparation method of efficient collecting agent

Abstract

The invention discloses an efficient collecting agent applied to low-grade copper-nickel sulfide ore and a preparation method of the efficient collecting agent. The collecting agent is prepared from the following raw materials in parts by weight: 30-50 parts of sodium isoamylxanthate, 10-30 parts of amine-alcohol xanthate, 10-30 parts of sodium dibutyl dithiophosphate,5-15 parts of diphenyl guanidine and 5-15 parts of methyl isobutyl carbinol, and the collecting agent is prepared by fully mixing the raw materials and uniformly carrying out stirring. The collecting agent has the characteristicsof collecting and foaming, and has good selectivity and obvious collecting effect on magnesium-rich low-grade copper-nickel sulfide ore; the size, color, luster and strength of flotation froth are stable, the mineralization degree of the froth is good, the floating speed of the ore is high, the concentrate grade and the copper-nickel recovery rate can be effectively improved, and the collecting agent is an ideal selective collecting agent for the low-grade copper-nickel ore.

Description

technical field [0001] The invention relates to the technical field of copper-nickel sulfide ore flotation auxiliary materials, in particular to a high-efficiency collector applied to low-grade copper-nickel sulfide ore and a preparation method thereof. Background technique [0002] With the deepening of mining, the nature of copper-nickel ore tends to be poor and miscellaneous, the difficulty of copper-nickel beneficiation increases, the quality of mixed concentrate is not high, the recovery rate of target minerals is low, and the comprehensive recovery of associated rare and precious metals is difficult. Conventional xanthate, black drug (such as butyl xanthate, isopentyl xanthate and butylamine black drug, etc.) collectors have many types, and the effect on copper-nickel ore with simple ore properties is better, but The effect on copper-nickel ore with severe mudification and low grade of raw ore is average, especially for minerals with fine particle size and complex ore ...

AI Technical Summary

Problems solved by technology

[0002] With the deepening of mining, the nature of copper-nickel ore tends to be poor and miscellaneous, the difficulty of copper-nickel ore dressing increases, the quality of mixed concentrate is not high, the recovery rate of target minerals is low, and the comprehensive recovery of associated rare and precious metals is difficult

Conventional xanthate, black drug (such as butyl xanthate, isopentyl xanthate and butylamine black drug, etc.) collectors have many types, and the effect on copper-nickel ore with simple ore properties is better, but The effect on the copper-nickel ore with severe mudification and low raw ore grade is average, especially for the minerals with fine particle size and complex ore properties, the separation effect is even worse.

Therefore, it is of great significance to screen efficient, economical and environmentally friendly mineral processing agents to solve the problems of low comprehensive recovery rate of useful minerals and high cost of agents.
