Gold ores chemical analysis methods
Part 13. Lead, zinc, bismuth, cadmium, chromium,
Determination of arsenic and mercury content
Inductively coupled plasma atomic emission spectrometry
Warning - Lead, cadmium, chromium, arsenic and mercury as toxic substances, the use of this part of the staff should have regular laboratory work experience. Headquarters
Points do not indicate all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and to ensure compliance with relevant national regulations
Prescribed conditions.
1 Scope
This part of GB/T 20899 specifies the determination of the amount of lead, zinc, bismuth, cadmium, chromium, arsenic and mercury in gold ores.
This section applies to the determination of lead, zinc, bismuth, cadmium, chromium, arsenic and mercury in gold ores, the determination of the elements in Table 1.
Table 1 measurement range
Elemental determination range Elemental determination range
Lead 0.0050% to 5.00% Chromium 0.010% to 2.00%
Zinc 0.0050% to 5.00% Arsenic 0.0050% to 5.00%
Bismuth 0.0050% to 2.00% mercury 0.0050% to 2.00%
Cadmium 0.0050% ~ 2.00%
2 method principle
The sample is dissolved in hydrochloric acid, nitric acid (determination of lead, zinc, bismuth, cadmium, arsenic and mercury) or dissolved in phosphoric acid (determination of chromium)
In the inductively coupled plasma atomic emission spectrometer selected conditions, the determination of the test solution of the spectral intensity of each element, with yttrium as the internal standard, press
Standard curve method for calculating lead, zinc, bismuth, cadmium, chromium, arsenic and mercury.
3 reagent
Unless otherwise specified, analytical reagents are used in the assay with either deionized or distilled water or rather pure water.
