Abstract

Using the dependences C(REE) = f(τ), fundamental differences in extraction of rare earth elements (REEs) from phosphate raw materials of sedimentary and igneous origin were identified, which consist in the extremal and monotonic plateauing behavior of the kinetic curves, respectively. The discovered features of nitric acid extraction of rare earth elements will make it possible to evaluate the prospects for integrated processing of raw materials and optimal conditions for their recovery from multicomponent systems.

从火成岩和沉积磷酸盐矿石中提取稀土元素的特点

利用依赖关系C(REE) = f(τ)，确定了沉积和火成岩磷酸盐原料中稀土元素提取的根本差异，分别表现为动力学曲线的极值和单调高原行为。硝酸萃取稀土元素的特性将有助于评价原料综合处理的前景和从多组分体系中回收稀土元素的最佳条件。
