| Abstract: | The paper introduces the method for quick determination of the iron content in the ores, in which the iron was quickly dissolved in the mixed acid of HCI-NH4F-HClO4 and reduced by adding into the zinc powder subsequently, the iron content in the ores was quickly determined with K2Cr2O7 solution.This method has wide uses with satisfied test results. RDS is between 0.060 - 0.080. |
