摘要
风化壳淋积型稀土矿是上世纪70年代初在我国江西省首次发现并最先被工业利用的新型外生稀土矿。40多年来,风化壳淋积型稀土矿浸取工艺经历了桶浸、池浸和原地浸取3个发展阶段,相应地形成了由传统到现代的3代浸取工艺。介绍了各种风化壳淋积型稀土矿浸取工艺的产生过程、技术特点和不足,并就风化壳淋积型稀土矿浸取工艺提出了一些见解。
Weathered crust elution -deposited rare earth ore is a new exogenous rare earth deposit which was first discovered in JiangXi province in the 1970＇s and has been applied in industry. The leaching process of weathered crust elution - deposited rare earth ore has experienced three stages which are bucket leaching, pond leaching and in - situ leaching. Accordingly, it has formed three generations of leaching process from tradition to modem. This paper introduces the generation process, technical features and deficiency of differ-ent leaching process of weathered crust elution - deposited rare earth ore and some views as to leaching process have been put forward.
