| Abstract: | The enrichment behaviour of Nickel through the emulsion liquid membrane system of Span80-TBP-NaOH has been studied.The enrichment condition of Nickel are as follows： Span-80=5 %;TBP=5%;paraffin=2 %;kerosene =88 %.Under the optimal operation conditions,the secondary extraction efficiency of Nickel（Ⅱ）from acidic leaching solution of laterite ores is onto 90%.The rate-control type of extraction process is given. |
