Abstract

The invention discloses a copper extracting agent. The copper extracting agent contains 20-25% of R1, 10-20% of R2 and 10-20% of R3 according to percentage by weight, the rest is solvent; wherein R1, R2 and R3 are randomly or independently selected from straight-chain paraffin radical of C8-C16.The copper extracting agent of the invention features good extracting property, good phase separability, high adaptability and stability, low price, thus being suitable for being promoted in industrialized production.

Description

technical field [0001] The invention relates to the technical field of copper smelting, in particular to a copper extractant. Background technique [0002] Copper hydrometallurgy mainly refers to copper smelting by leaching, extraction, and electrodeposition. This method includes three process steps: leaching, extraction, and electrodeposition. Extraction is the key step of the method, and the most critical step in the extraction process is the extraction of copper extractant. choose. At present, the copper extractant used in the copper smelting industry generally has the problem of high price, which reaches 160,000 to 200,000 yuan per ton, and most of the copper extractants have poor extraction performance and are unstable. Contents of the invention [0003] The object of the present invention is to provide a copper extraction agent. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a copper extractant containing ...
