Determination of impurity elements in imports of copper concentrate Inductively coupled plasma atomic emission spectrometry1 ScopeThis standard specifies the method for determination of copper concentrate imports of lead, zinc, cobalt, nickel, magnesium, cadmium, arsenic, antimony, bismuth, mercury and other nutrient contents. This standard applies to the determination of imported copper concentrates of lead, zinc, cobalt, nickel, magnesium, cadmium, arsenic, antimony, bismuth, mercury and other elements in the content determination of each element Fan Wai in Table 1. Table 1 of the elements of the measurement range in% Element measurement range (mass fraction) Lead 0.01 to 6.0 Zinc 0.01 to 6.0 0.01 to 2.0 cobalt Nickel 0.005 to 1.0 Magnesium 0.001 to 3.0 Element measurement range (mass fraction) Cadmium 0.001 to 0.5 Arsenic 0.005 to 1.5 Sb 0.01 to 1.0 Bismuth 0.01 to 0.5 Mercury 0.001 to 0.12 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
