%X 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.
