This standard describes the method for the determination of iron content in gold ores, which is suitable for samples with a mass fraction of 1.00% to 10.00%. The standard stipulates that after dissolving the sample with muriatic acid, nitric acid and sulfuric acid, the method for the determination of ammonia chloride settling, sodium tungstate indicator and potassium dichromate standard titration solution is used. The method aims to ensure the accuracy of iron content determination and provide a basis for the quality control of gold ores.
