埃及核材料管理局Monir M.Aly等提出了一种用HNO_3作浸出剂处理磷灰岩矿回收镧系元素的工艺。这种新工艺不会影响化肥生产的标准工艺流程。同时,为了富集化肥并回收氯气,进行了浸出液脱氟的试验。从这种磷灰岩矿回收镧系元素的优点是由于它们的镧系元素含量比较高(平均0.11％),而生产的化肥铀含量较低(平均25mg/kg)。因 Monir M. Aly et al proposed a process for the recovery of lanthanides from apatite ore using HNO 3 as a leaching agent. This new process does not affect the standard process for fertilizer production. At the same time, in order to enrich the fertilizer and recover the chlorine, the leachate defluoridation test was carried out. The advantages of recovering lanthanides from such apatite deposits are due to their relatively high lanthanide content (0.11% on average) and lower production of uranium (25 mg / kg on average). because
