摘要
通过对石寺-北冶煤下铝土矿伴生稀土元素的系统分析,探讨了稀土元素富集特征及富集机制。研究认为:稀土元素配分曲线具有较明显的右倾特征,属轻稀土富集型;稀土元素在含铝岩系的中下部较富集,稀土元素总量与P_(2)O_(5)含量呈明显的正相关性,这可能与矿石中的独居石有关,但稀土元素的赋存形式仍需要进一步研究;沉积环境的酸碱性对稀土元素的富集有着重要的影响,碱性环境有利于稀土元素的富集;豫西地区含铝岩系中伴生的稀土元素资源潜力巨大,应建立此类型伴生稀土矿床的评价指标体系,同时应加大科研投入,突破在工业赤泥中提取稀有、稀土金属的技术瓶颈。
Based on the systematic analysis of rare earth elements(REE) associated with bauxite under Shisi-Beiye coalbed,the enrichment characteristics and enrichment mechanism of rare earth elements are discussed.The research indicates that the distribution curve of rare earth elements has obvious right dip characteristics,which belongs to light rare earth enrichment type;Rare earth elements are enriched in the middle and lower part of aluminous rock series,and there is an obvious positive correlation between the total amount of rare earth elements and the content of P_(2)O_(5),which may be related to monazite in the ore,but the occurrence form of rare earth elements still needs to be further studied;The acidity and alkalinity of sedimentary environment have an important influence on the enrichment of rare earth elements,and alkaline environment is conducive to the enrichment of rare earth elements;The associated rare earth element resources in aluminous rock series in western Henan have great potential.The evaluation index system of this type of associated rare earth deposit should be established.Meanwhile,scientific research investment should be increased to break through the technical bottleneck of extracting rare and rare earth metals from industrial red mud.
