Zinc concentrate copper, silicon, magnesium, zinc, aluminum, Determination of iron content X-ray Fluorescence Spectrometry

1 Scope

This standard specifies the X-ray fluorescence spectrometric method zinc concentrate copper, silicon, magnesium, zinc, aluminum and iron content.

This standard applies to zinc concentrate and zinc ores - Determination of the content of the following ingredients, measuring range in Table 1.

Table 1 zinc concentrate in the measurement range of each component% (mass fraction)

Component measurement range Cu 0.11 ~ 0.75 SiO2 2.16 ~ 33.01 MgO 0.085 ~ 0.96 Zn 20.41 ~ 52.70 Al2O3 0.57 ~ 7.66 Fe 4.13 ~ 15.20 S 15.16 ~ 32.00 Pb 1.44 ~ 3.90 CaO 0.96 ~ 4.65 as 0.064 ~ 0.21 K2O 0.18 ~ 2.13 Cd 0.054 ~ 0.13 Mn 0.025 ~ 0.26 Note. This standard Determination of zinc concentrate by S Pb CaO, As, K2O Cd, content,,, Mn component, just as the results of the analysis in the laboratory, not as a subject the results of the survey report.
