Determination of High-content Sulfur in Ores by Infrared CarbonSulfur Analyzer

A method for the determination of high content of sulfur in ores by infrared carbon-sulfur analyzer was developed. The factors influencing the determination were discussed, including selection of standard samples, balancing error, sample mass tested, fully burning of the samples and stability of the instrument. And the study results showed that the method is suitable for the determination of high-content sulfur in ores.
