Abstract: The measurement of the sulfur in chromium ores and concentrates using high frequency combustion infrared-adsorption method is studied. The instrument working parameters, optimal testing conditions and disturbance of impurities are discussed. This method, simple and rapid, can greatly improve the working efficiency, with the measurement scope of 0.001% ~ 0.004%.

Key words: High frequency combustion infrared-adsorption method, Chromium ore, Sulfur
