YS/T 1115.9-2016 in English

This standard outlines the methods for determining sulfur content in copper ores and tailings. It specifies two analytical procedures: the high-frequency infrared absorption method and the combustion-iodate titration method. The procedures are designed to ensure consistent and reliable results in chemical analysis. The standard provides detailed guidelines on sample preparation, equipment calibration, and measurement techniques. It covers the principles, reagents, instruments, and operational steps required for accurate sulfur quantification. The methods are applicable for use in laboratories involved in the analysis of copper mineral samples. The standard also includes information on safety precautions and quality control measures to ensure the accuracy and precision of the analytical process.
