This standard specifies the determination method of tantalum and niobium content in tungsten concentrates. It is suitable for the determination of tantalum (five oxidation tantalum) and niobium (five oxidation diniobium) in tungsten concentrates, and the measurement range covers the mass fraction of five oxidation tantalum 0.020% to 1.00% and the corresponding range of five oxidation diniobium. The methods include plasma emission Light spectrum method and Spectrophotometric method, spectrophotometry, to ensure accurate analysis of tantalum and niobium content.
