摘要

Separation of copper,zinc,cobalt and nickel ions from synthetic leach liquor using supported liquid membrane was studied.LIX 84I,TOPS-99 and Cyanex 272 were used as the mobile carrier for the supported liquid membrane.From the synthetic leach liquor containing 8.97mole/m3 copper,40.83 mole/m3 zinc,27.49 mole/m3 cobalt,420.51 mole/m3 nickel and 75.677 mole/m3 ammonium sulphate,copper was first separated using LIX 841 followed by zinc using TOPS-99 and cobalt using Cyanex 272.The solution was made copper free using 10% LIX 84I in the membrane phase and 900 mole/m3 H2SO4 in the strip solution at pH 4.5.After copper was separated,the leach liquor was made zinc free at pH 3.65 using 0.15 M TOPS-99 in the membrane phase and 900 mole/m3 H2SO4 in the strip solution followed by separation of cobalt using Cyanex 272.It was observed that co-permeations of zinc,cobalt and nickel with copper using LIX 841 were 0.076,0.085 and 0.10 mole/m3,respectively.Co-permeations of cobalt and nickel with zinc using TOPS-99 were 0.187 and 0.323 mole/m3 and co-permeation of nickel with cobalt using Cyanex 272 was 3.407 mole/m3,respectively.Separation factors for metal ions with different extractants were calculated and reported.
