摘要
介绍了新型萃取器──矮型斜底箱式混合澄清器及利用此萃取器从含铀煤灰酸浸矿浆中萃 取铀的小型试验与连续台架试验结果及影响溶剂损失的主要因素。试验结果表明，处理１ｔ含铀 煤灰，损失胺１５６ｇ；生产１ｋｇ铀，实际损失胺５４ｇ。推测，若使用溶解度更小的三脂肪胺，可能会 取得更满意的结果。
A new type of extractor, low type for mixer-settler with sloping bottom, and small-scale and continuous bench-scale tests results of extracting uranium from acid leaching pulp of coal ash containing uranium using this extractor were described. The factors affecting solvent loss were determined. The results showed that amine was losted 156g and 54g when curing 1 t of coal ash con taining uranium and producting 1 kg uranium respectively. If trialkylamine with lower solubility was used in test, better results would be obtained.
