GB/T 14949.6-2021 Focusing on the composition detection of manganese ore, the content of copper, lead and zinc in it is determined by flame atomic absorption spectroscopy (AAS). This standard applies to all kinds of manganese ore. It details the determination principle, clarifies the technical indicators of the required instruments and equipment, and standardizes the selection and preparation of reagents. There are strict regulations on the collection, preparation and analysis steps of the sample, covering the whole process from sample weighing, dissolving to final determination. Provide a unified and reliable method for the accurate determination of copper, lead and zinc content in manganese ore, and help the mass evaluation of manganese ore and related industrial applications.
