Abstract: he high frequency infrared adsorption method can measure 1%~3% high sulfur content in iron ore, lifting the upper limit of sulfur in iron ore measureable by high frequency infrared carbon-sulfur analyzer. The method is proven to have good precision, linear correlation coefficient and recovery, providing a theoretic basis for the extension of the national standard.

Key words: Iron ore, High content sulfur, High frequency infrared absorption method
