用胺从矿石浸出液中萃取铀和钼的研究已有不少报道。一般都用叔胺萃取铀和钼,然后在反萃取或在反萃取液沉淀铀的过程中使铀钼分离。从含钼高的液溶中萃取铀,钼时,萃取常会发生困难,当有机相中钼含量高达一定量时,杂多钼胺络合物即可能沉淀,严重地影响萃取操作,造成大量的溶剂损失。某厂在用0.1M 三脂肪胺(TFA)萃取钼时,为了防止钼胺络合物的沉淀,添加了25%TBP,钼的操作容量10克/升,但高
There have been many reports on the extraction of uranium and molybdenum from ore leachate using amines. Uranium and molybdenum are generally extracted with tertiary amines and then uranium and molybdenum are separated during the stripping or during the precipitation of uranium from the stripping solution. Extracting uranium and molybdenum from liquid with high molybdenum content often leads to difficulties in extraction. When the content of molybdenum in the organic phase is up to a certain amount, the complex of molybdenum complex may precipitate, which will seriously affect the extraction operation and cause a large amount of Solvent loss. When a plant extracted molybdenum with 0.1M tri-fatty amine (TFA), 25% TBP was added to prevent the precipitation of the molybdenum amine complex and the operating capacity of molybdenum was 10 g / l but high
