GB/T 3884.3-2012 《Methods for chemical analysis of copper concentrates - Part 3: Determination of sulfur content - Gravimetric method and Combustion-titration method》 Related products

This standard specifies methods for the determination of sulfur content in copper concentrates, including the weighting method and the combustion-Titrimetric method. The weighting method is suitable for the determination of sulfur content in the range of 1.00% to 42.00%, while the combustion-Titrimetric method is suitable for the determination of sulfur content in the range of 10.00% to 42.00%. The weighting method calculates the sulfur content by using sodium carbonate and zinc oxidation semi-melted samples at 750 ° C, followed by barium chloride settling sulfate, burning and weighing. The combustion-Titrimetric method involves high-temperature combustion of samples, using appropriate indicators and titration solutions to determine the sulfur content. These methods are suitable for accurate analysis of sulfur content in copper concentrates, ensuring accuracy in production and quality control.
