Paper Title:
A New Copper Extractant and its Extraction Performances in Sulfate Medium
  Abstract

Employed methanol, toluene, formaldehyde, 4-tert-octylphenol, and hydroxylamine as raw materials, triumphantly obtained a new extractant for copper by the processes of salinization reaction, formylation reaction, oximate reaction and so on, the purity of new extractant is > 98% by purity test. The extraction performances are very perfect. The maximal extraction efficiency is up to 90.4% for Cu2+ by single-stage extraction, and recovering Cu2+ in 170g/L H2SO4 medium by stripping, stripping of copper >99.3% can be obtained. The preparation cost of the extractant is very low. It can contribute to better development of hydrometallurgy for copper, and gradually reduce dependence of Chinese copper industries on overseas corporations.
