GB/T 6730.49-2017 is a relevant standard for iron ore detection. It uses flame atomic absorption spectroscopy (AAS) to determine the potassium content in iron ore. It is suitable for natural iron ore, iron concentrate, sinter and pellet. The standard details the determination principle, sets requirements for required instruments and equipment, and standardizes the preparation of reagents, specimens, and analysis procedures. The measurement range (mass fraction) is 0.005% -2.00%, which provides a unified and reliable method for the accurate determination of potassium content in iron ore. It is of great significance for evaluating the quality of iron ore and related production applications.
