摘要
详细研究了某选矿厂尾矿的化学成分、矿物组合、以及稀土元素的赋存形式、稀土矿物的分布特征和解离性等，阐明了该原料中稀土的赋存状态。据此提出了重—浮联合流程综合回收稀土的方案，并通过小型选矿试验进行了验证。研究结果为其综合利用提供了基础资料和理论依据。
Detailed study was carried on the tailing ore of a dressing plant about the chemical composition,minerals assemblage,distribution of rare earth elements(REE),as well as the distribution characteristics and its dissociation.It expounds the distribution situation of REE in the raw material and suggests a combined dressing circuit of gravity and flotation to recover the REE which is examined by small scale dressing experiment.The study provides some basic data and theoretical evidences.
