Scope
Main technical content: This document describes the principles, reagents and materials, instruments and equipment, analytical steps, data processing, quality control, precautions, and waste disposal of the determination method for niobium and tantalum in polymetallic ores. This document is applicable to the determination of niobium and tantalum content in polymetallic ore samples. The method's detection limit (3S) is: niobium 0.062 μg/g, tantalum 0.042 μg/g; the niobium determination range is 0.25 μg/g to 500 μg/g, and the tantalum determination range is 0.17 μg/g to 500 μg/g.
