The GB/T 6730.36-2016 standard specifies a method for the determination of copper content in iron ore using flame atomic absorption spectroscopy (AAS). Applicable to natural iron ores, iron concentrates and lumps, including the determination of copper content in sintered products, the measurement range is 0.004% to 0.8% (mass fraction). The standard describes in detail the sample pretreatment method and analysis process, and calculates the copper content by measuring the copper Absorbance in the air-acetylene flame. Standard documents related to the specifications of the analytical laboratory water, the preparation of the pre-drying sample for iron ore analysis, the method of sampling and sample preparation of iron ore, and the laboratory Glass instrument are cited in the standard to ensure the accuracy and repeatability of the measurement process.
