Extraction of copper from leaching solution at high temperature

摘要

It includes contacting an aqueous solution containing copper at a temperature of at least 30 ℃, and a formula extracting reagent (I),R is a group of linear or treelike c10-c18 tar, R1 is h or CH3, including a diluent and a selected mat, a node, a ter and an alcohol reformer. The best reagent is 5-dodecene acrylonitrile, 2-hydroxy-5-dodecyl phenoxy, 5-decabromodiphenoxy, 2-hydroxy-5-decabromodiphenoxy, 2-hydroxy-5-decabromodiphenoxy
