Application Summary AI generated

This standard specifies the inductively coupled plasma mass spectrometry (ICP-MS) method for determining niobium, tantalum, zirconium, hafnium, and 15 rare earth elements in tungsten and molybdenum ores. It is applied in geological exploration, mining, and mineral processing industries for accurate multi-element analysis of ore samples. The method supports resource evaluation, quality control, and environmental monitoring in tungsten and molybdenum mining operations.
