Application Summary AI generated

This standard specifies the inductively coupled plasma atomic emission spectrometry (ICP-AES) method for determining twelve elements in tungsten and molybdenum ores, including bismuth, cadmium, cobalt, copper, iron, lithium, nickel, phosphorus, lead, strontium, vanadium, and zinc. It is applied in mining and mineral processing laboratories for quality control, resource evaluation, and environmental monitoring of tungsten and molybdenum ore samples. The method ensures accurate multi-element analysis essential for ore grade assessment and metallurgical process optimization.
