Determination of the amount of gold and silver by flame atomic absorption spectroscopy and fire assay; --- Part 3. Determination of sulfur content - Gravimetric and combustion - titration; --- Part 4. Determination of magnesium oxide content - Flame atomic absorption spectrometry; --- Part 5. Determination of the amount of fluorine ion selective electrode method; --- Part 6. Determination by flame atomic lead, zinc, cadmium and nickel absorption spectrometry; --- Part 7. Determination of lead content Na2EDTA titration; --- Part 8. Determination of zinc contents Na2EDTA titration; --- Part 9. Determination of the amount of arsenic and bismuth hydride generation - atomic fluorescence spectrometry, potassium bromate titration and diethyl ammonia Silver group acid spectrophotometry; --- Part 10. Determination of antimony content hydride generation - atomic fluorescence spectrometry; --- Part 11. Determination of mercury content - Cold atomic absorption spectrometry; --- Part 12. Determination of the amount of fluorine and chlorine ion chromatography; --- Part 13. Determination of the amount of copper electrolysis; --- Part 14. Determination of the amount of gold and silver fire assay gravimetric method and atomic absorption spectrometry. This section GB/T 3884 Part 13. Rules in this section in accordance with GB/T 1.1-2009 given draft. This section uses the translation method identical with ISO 10469.2006 "Determination of copper sulphide concentrate electrolysis." This part of ISO 10469.2006 main differences are as follows. --- English name made the change; --- With a decimal point instead of a comma as the decimal point in the international standard ",". ","; --- With a period instead of a full stop in the international standard. "". ""; --- With "this Part" instead of "this International Standard"; --- According to Chinese customary change the standard name; --- Remove the cover of the international standards, directory, foreword and introduction. The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized. This section is responsible for drafting unit.

3 Method summary

With sulfuric acid and nitric acid to dissolve the sample, and then separated from interfering elements copper and silver by precipitation with silver chloride;. Hydrobromic acid was added and arsenic, Antimony, selenium and tin form volatile substances are separated; with sodium thiosulfate copper sulfide and iron separation, or by generating ferric hydroxide precipitate points From iron, bismuth and tellurium. When nitric acid, sulfuric acid and a small amount of chlorine ions, electrolytic deposition of copper, and molybdenum in this case does not precipitate. Electrolysis residue sulfide Copper precipitation and precipitation filtrate and all traces of residue are copper by flame atomic absorption spectroscopy or inductively coupled plasma atomic emission Spectrometry. When mercury is greater than or equal to 0.005% of copper needs to be determined in the mercury content of correction, but no steps in this section Provisions.

4 Reagents

Analysis, the reagents were of analytical grade, the water used for the same purity distilled water or water. 4.1 nitric acid (ρ20 = 1.42g/mL). 4.2 nitric acid (11). was added slowly with stirring 500mL of nitric acid (4.1) to 500mL of water. 4.3 sulfate (ρ20 = 1.84g/mL). 4.4 sulfate (11). was added slowly with stirring 500mL of sulfuric acid (4.3) to 500mL water cooling.
