中文摘要：
文章评述了40年来风化壳淋积型稀土矿的基础研究,包括矿床的成因及特征、稀土矿物的组成及性质,稀土与黏土矿物的关系、稀土在黏土矿物中的吸附及迁移理论,论述了风化壳淋积型稀土矿的稀土元素配分的特征及四大效应,并探讨了稀土浸出机理和风化壳淋积型稀土矿稀土浸取的三代工艺,提出了风化壳淋积型稀土矿基础研究和浸出工艺的发展方向及亟待解决的问题.
英文摘要：
The basic research was reviewed about the weathered crust elution-deposited rare earth ore for over forty years, including the causes and the characteristics of the deposit, the compositions and properties of rare earth ore, the relationship between rare earth ore and clay mineral as well as the theory of the adsorption and migration of rare earth in the clay mineral. Great attentions were also paid to the characteristics of the rare earth element partitioning and the four major effects in the weathered crust elution-deposited rare earth ore. The leaching mechanisms were investigated and the three generation leaching technologies of the weathered crust rare earth ore were also reviewed. The fundamental research, the development of the leaching technology and the problems which should be resolved urgently in the weathered crust elution-deposited rare earth ore were pointed out.
