Problems solved by technology

However, the recovery of copper cannot be taken into account, which reduces the recovery rate of copper
[0005] The general defect in the above content is that due to the large difference in the buoyancy of copper and molybdenum, there are differences in the pharmaceutical systems of the two, and the actual production cannot take into account the collection of copper and molybdenum. Inclusion of pyrite and other gangue minerals lead to low concentrate grade, good selectivity and weak collection capacity lead to low recovery rate and waste of resources

Abstract

The invention provides a collecting agent and a preparation method and application thereof. The collecting agent comprises a combination of N, N-diethyl dithiocarbamic acid propionitrile ester, methyl isobutyl carbinol, alkylphenol polyoxyethylene ether and diesel oil. Through compounding of N, N-diethyl dithiocarbamic acid propionitrile ester, methyl isobutyl carbinol, alkylphenol polyoxyethylene ether and diesel oil, the collecting agent has excellent solubility, dispersity and flowability; the collecting agent is good in copper-molybdenum ore selectivity and high in collecting capacity, can obtain high-grade and high-recovery-rate copper-molybdenum concentrate, and can achieve a good flotation effect with a small dosage in the ore dressing process; and meanwhile, the collecting agent is wide in raw material source, simple in preparation process and good in application prospect.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a collector and its preparation method and application. Background technique [0002] The proven porphyry copper deposits in the world account for about 76% of the total copper, and the associated molybdenum in porphyry copper deposits is an important source of molybdenum metal. In line with the concept of sustainable development and resource conservation, the efficient treatment of copper-molybdenum ore and the collection of copper-molybdenum metals have attracted more and more attention. [0003] Most of the prior art adopts mixed flotation method to process copper-molybdenum ore, mainly adopting esters (ethylthiocarbamate, ester-105, etc.), xanthates (ethylxanthate, butylxanthate, etc.), black medicines ( Ammonium butyl ammonium black medicine, sodium isobutyl black medicine, etc.) and hydrocarbon oils (kerosene, diesel oil, etc.) are used as collectors...
