| Abstract: | This paper introduced determination of SiO： in iron ore using NaOH fusion, distilled water extraction, hydro- chloric acid neutralization and acidification, fluoride deploymerization and ammonium molybdate coloration. This meth- od has detection limit of 0.10%. It was performed on national first-grade iron ore standard to confirm the accuracy and precision of the method. The test results conformed to the standard, with relative standard deviations less than 10% for 12 determinations. |
