| Abstract: | This paper studies the conditions of separation and enrichment for trace copper and finds out a new Liquid Membrane system: P204 -N205 - Kerosine - HCI. Also the paper finds out the best conditions about enrichment. The result shows that the copper recoveries over 95 % are achieved with up to hundred fold enrichment. |
