- CAUTION: Personnel using this standard should have practical experience in formal laboratory work. This standard does not address all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This part of GB/T 17415 specifies the method for the determination of tantalum in tantalum and niobium ores by butyl rhodamine B photometry. This part applies to tantalum and niobium ores, and also applies to the determination of tantalum in lithium, rubidium and cesium ores. Measuring range: 0.0050% ~ 1.0% (mass fraction) tantalum content (calculated as tantalum pentoxide).
