Problems solved by technology

It has good extraction ability, fast extraction speed and high copper recovery rate, but because the extraction ability is too strong, it is difficult to back-extract. At the same time, the stability and oxidation resistance of the extraction agent are not ideal, and the adaptability is poor.

Abstract

An extractant for copper contains hydroxyketoxime, hydroxyaldoxime, kerosene, tridecaneol and 2,4,6-tritert-butylphenol through proportionally mixing. Its advantages are optimal phase-separation power, high effect, low dosage and high recovery rate of copper.

Description

(1) Technical field [0001] The invention relates to a copper extractant, which belongs to the field of chemical materials. (2) Background technology [0002] At present, the copper extractant is a combination of a single hydroxyketone oxime or hydroxyaldoxime and a solvent abroad. There are certain deficiencies in the extraction performance. The alkyl group connected to the carbonyl carbon atom of hydroxyketoxime has good phase separation, and the extraction agent is less consumed, but the extraction speed is slow, while the carbonyl carbon of hydroxyaldoxime Attached to the atoms is a hydrogen atom. It has good extraction ability, fast extraction speed, and high copper recovery rate, but because the extraction ability is too strong, it is difficult to back-extract. At the same time, the stability and oxidation resistance of the extraction agent are not ideal, and the adaptability is poor. (3) Contents of the invention [0003] Purpose of the present invention is just in...
