In this paper, the sulfur content in copper concentrate was determined by high frequency infrared carbon sulfur determinator, and the optimum instrument condition parameters were determined. At the same time, the sample weight and flux addition of copper concentrate samples were studied. The experimental results show that the high frequency infrared carbon sulfur determinator can quantitatively determine the sulfur content in copper concentrate samples, and the relative standard deviation is 0.30%-0.51%. The results are in good agreement with the results of combustion-titration method. Using high frequency infrared carbon sulfur determinator to determine the sulfur content in copper concentrate, can effectively shorten the time of sulfur analysis and detection, and realize the rapid determination of sulfur. The precision and accuracy are high, which meets the requirements of production control.
