| Abstract: |
| The separation of copper and iron from high copper and low iron sulfated solution with P507, which was leached under pressure from gold copper concentrate, was investigated. Iron was extracted from concentrate leaching solution with P507, then use 0.01 mol/L H2SO4 to wash the organic phase, and stripping with 6.0mo/L HC1. The Na2CO3 solution was used to seperate copper, and the deposition was dissolved by H2SO4 which can be electrolyzed straightly. The coefficient of iron and copper is 1 030. The recovery rate of copper is 96.26%. |
