| 摘 要： | 研究了用P507的煤油溶液作为萃取剂，从酸性硫脲(TU)浸金液中回收金的性能. 用浓度为1.65 mol/L的P507萃取剂在料液H2SO4]＝0.335 mol/L, 相比O/A=1:1，两相接触时间5 min的条件下萃取金，得到金的一级萃取率达99.80%；用50 g/L的Na2SO3溶液反萃，一级反萃率达82.45%，同时达到金、铁的分离.

| Abstract: | The performance using P507 to extract gold from gold-leaching acidic thiourea solution was investigated. Gold was extracted by P507 of 1.65 mol/L in kerosene under the conditions of H2SO4 concentration 0.335 mol/L, phase ratio 1:1 and time of contact 5 min. The percentage extraction in a single stage reached 99.80%. When 50 g/L Na2SO3 was used for stripping, the percentage stripping in one stage reached 82.45%, and gold was separated from iron by stripping operation. |
