1 Scope

This method specifies the method for determination of sulfur content in copper concentrate. This method is applicable to the determination of copper concentrate sulfur content measurement range of 1. 1.00% - 42.00%; Tier 2 measuring range. 10.00% ~ 42.00%. 2 1 gravimetric method 2.1 Method summary Sample by sodium carbonate, after the semi-molten zinc oxide, dissolved in water at 750 ℃ \u200b\u200bsoluble, with barium chloride solution sulfate precipitate After filtration, burning weighed mass of barium sulfate sulfur content of the sample calculation. In the compound to be tested, less than 5mg fluoride does not interfere with the determination. 2.2 Reagents Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity. 2.2.1 sintering agent. a copy of the anhydrous sodium carbonate is mixed with a zinc oxide, fine, and mix. 2.2.2 hydrochloric acid (ρ1.19g/mL). 2.2.3 nitrate (ρ1.42g/mL). 2.2.4 barium chloride solution (100g/L), filtered to use. 2.2.5 silver nitrate solution (10g/L). Per 100mL was added 3-4 drops of nitric acid (2.2.3). 2.2.6 methyl orange indicator (1g/L). 2.3 Sample 2.3.1 The sample size should be less than 100μm. 2.3.2 Samples should be 100 ℃ ~ 105 ℃ baking 1h, placed in a desiccator, cool to room temperature. 2.4 Analysis Steps 2.4.1 Sample Table 1 sample was weighed, accurate to 0.0001g. ......
