For the treatment of high-grade tantalite & niobite and low-grade tantalum ilmenorutile,para-octanol solvents with different concentration can be used to improve the product quality,recovery of Ta and Nb and the operating conditio.
用三种不同浓度的工业仲辛醇对钽铌的萃取与反萃性能的影响进行了研究，结果表明：不同浓度的仲辛醇对钽铌的萃取与反萃取性能有差异，处理高品位钽铌铁矿和低位品钛铌钽矿时，采用不同浓度的仲辛醇有可能提高钽铌产品质量，提高钽铌实收率和改善操作条件。
Experiment is done on the acid hydrolysis of titanium-columbite-tantalite ore difficult to decompose.
对难分解的钛钽铌矿的酸分解工艺进行了试验研究。
