Method for measuring sulfur content in copper concentrate

The invention relates to a method for measuring the sulfur content in copper concentrate, and belongs to the technical field of methods for measuring the sulfur content in the copper concentrate. The method comprises the following steps: (1) calibrating a sodium hydroxide standard solution by using magnesium sulfate and a combustion titration method sulfur determination device; calculating the actual concentration according to the following formula, and taking the average value as the concentration of the sodium hydroxide standard titration solution; c is equal to # imgabs0 #; (2) determination of sulfur content; and (2) determining the sulfur content by using the sodium hydroxide standard titration solution calibrated in the step (1) according to a determination method specified in 3.5. 2 in GB/T3884.3-2012. When the determination method is used for carrying out traceability analysis on the certified sulfur concentrate standard substance, the value of the determination result is closer to the true value comp
