混合沉降装置萃取钽和铌朝鲜能源研究所工艺设备试验室使用一种试验规模的混合沉降装置，用ＴＢＰ从ＨＦＨ＿２Ｏ溶液系统中萃取钽和铌。所用原料溶液的Ｈ＿２ＳＯ＿４浓度影响钽和铌的萃取率及杂质的萃取特性。通过条件试验使钽、铌的萃取率达到９９％以上。为了除去有机...
Tandem and Niobium Extraction with Mixed Settlements The North Korea Energy Research Institute Process Equipment Laboratory used a pilot scale hybrid settler to extract tantalum and niobium from HFH2O solution systems using TBP. The H 2 SO 4 concentration of the feed solution used affects the extraction rate of tantalum and niobium and the impurity extraction characteristics. Through the condition test so that the extraction rate of tantalum, niobium reached more than 99%. In order to remove organic ...
