T he effect of high silicate on the determination of gold in geological samples by activated carbon absorption and iodimetry method was mainly observed . The effects of silicate were discussed , and its elim-inating method was given also . Recovery of gold by the method was 95 .0% ~103 .3% . This method im-proved the accuracy of analysis results . The analysis results were consistent with fire assay weight meth-od . The method was quick , accurate , low cost and low pollution .
