　　Copper(Ⅱ) was extracted from ammoniacal/ammonium chloride solutions using ketoxime N910 as carrier.The effect of extraction time, extractant concentration and phase ratios on copper(Ⅱ)recovery had been investigated.The experimental results showed the extraction process was very fast and almost quantitative extraction was observed in most cases in just one-minute of contact.The copper extraction rates increase constantly with extractant concentration and phase ratios.
