The invention relates to a technique for removing sulphur ions in pregnant solution and improving the grade of gold mud, which has the advantage of well solving the problem of the influence of the S<2-> ions in the pregnant solution for the grade of the gold mud in the replacement process of the pregnant solution. The method comprises the following steps that: lead salt is added before the replacement of the pregnant solution to generate a certain amount of Pb<2+> ions, and the generated Pb<2+> ions can react with the S<2-> ions in the pregnant solution, thus reducing hazardous anions. The reaction process is as follows: Pb<2+>+S<2->->PbS(sediment), and finally the content of the S<2-> ions in the pregnant solution is reduced to be below 2mg/l. The method is applicable to the cyaniding process of removing the sulphur ions in the pregnant solution before the replacement of the pregnant solution, thus achieving the purpose of improving the grade of the gold mud.
