The method for the recovery of tantalum and niobium was developed for use on secondary raw materials in the form of oil-contaminated sludge. Uchino and Azuma [486] suggested using solid-liquid separation of oil from the slurry prior to the recovery of tantalum and niobium from the raw material. 

Uchino and Azuma [498] proposed a way in which to recycle the filtrate solutions. The process consists of adding calcium hydroxide, Ca(OH)2, to the filtrate, yielding a calcium fluoride, CaF2 precipitate and gaseous ammonia, NH3. The fluorine and ammonia are recovered in forms that are suitable for reutilization. 

Uchino and Azuma [504] developed and proposed a two-step calcination process of tantalum and niobium hydroxides to obtain oxides. The first treatment is recommended to be performed at 500-700°C, and the second- at 750-1000°C. It is reported that the above method ensures the production of oxides that contain only negligible concentrations of fluorine and silicon impurities.
