1 Scope

This part of GB/T 8151 specifies the determination of copper, lead, iron, arsenic, cadmium, antimony, calcium and magnesium in zinc concentrates. This part is applicable to the determination of copper, lead, iron, arsenic, cadmium, antimony, calcium and magnesium in zinc concentrate. The range of each element is shown in Table 1. Table 1 Determination of each element Determination of elemental mass fraction /% Calcium 0.10 ~ 5.00 Magnesium 0.10 ~ 5.00 Cadmium 0.050 ~ 2.00 Arsenic 0.10 ~ 5.00 Antimony 0.030 ~ 0.50 Copper 0.10 ~ 5.00 Lead 0.10 ~ 5.00 Iron 1.00 ~ 10.00

2 method summary

The samples were decomposed with nitric acid, hydrochloric acid, hydrofluoric acid and perchloric acid. In 5% hydrochloric acid medium, the samples were characterized by inductively coupled plasma atomic emission spectroscopy Method, at the selected wavelength of each element to determine the emission intensity, according to the standard working curve method to calculate the quality of the elements of the fraction.

3 reagent

Unless otherwise stated, only the reagents identified as excellent grade pure and distilled water or deionized water or comparable purity are used in the analysis. 3.1 Hydrochloric acid (ρ1.19g/mL). 3.2 nitric acid (ρ1.42g/mL). 3.3 hydrofluoric acid (ρ1.15g/mL). 3.4 perchloric acid (ρ1.67g/mL). 3.5 Hydrochloric acid (1 1). 3.6 nitric acid (1 1). 3.7 Calcium Standard Storage Solution. 2.4971g of calcium carbonate (wCaCO3≥99.99%) previously dried at 120 ° C was placed in 400 mL of Cup, add 20 mL of water, then add hydrochloric acid (3.5) to complete dissolution, then add 10mL hydrochloric acid (3.1), boil to remove carbon dioxide, take ......
