T/HNNMIA 15-2024 Chemical analysis method for gold ore determination of copper, lead, zinc, iron, manganese, potassium, sodium, calcium, and magnesium content - Inductively coupled plasma atomic emission spectroscopy

Scope

Main technical content: This document describes the method of determining the content of copper, lead, zinc, iron, manganese, potassium, sodium, calcium, and magnesium in gold ores using inductively coupled plasma atomic emission spectrometry. This document is suitable for the determination of copper, lead, zinc, iron, manganese, potassium, sodium, calcium, and magnesium in gold ores, and other polymetallic ores can also be referenced for determination. The determination ranges of each element are shown in Table 1. Table 1: Determination ranges (unit: percentage) Element Determination range Element Determination range Cu 0.01～10.00 K 0.02～10.00 Pb 0.01～10.00 Na 0.02～10.00 Zn 0.01～10.00 Ca 0.05～10.00 Fe 0.05～20.00 Mg 0.05～10.00 Mn
