贵州清镇暗流云峰铝土矿稀土元素分布规律研究

Study on the distribution law of rare earth elements in Yunfeng bauxite mine in Qingzhen,Guizhou

暗流云峰铝铁矿位于黔中铝土矿成矿区北部,区域成矿地质条件优越,资源丰富,根据等离子质谱法分析结果显示,矿区内稀土元素含量较贵州省内其他铝土矿区高,可能具有较大的经济价值,本文主要探讨铝土矿及围岩的矿石类型、化学成分、矿物成分与稀土元素含量之间的关系,发现稀土元素含量与粘土矿物含量基本呈正相关性,而白云石、方解石等不利于稀土元素的富集,同时应加大对省内含铝岩系中稀土元素的研究,保证资源的合理利用。

Undercurrent Yunfeng bauxite mine is located in the north of the bauxite forming area in Central Guizhou.The regional metallogenic geological conditions are superior and the resources are rich.According to the analysis results of plasma mass spectrometry,the content of rare earth elements in the mining area is higher than that in other bauxite mining areas in Guizhou Province,which may have greater economic value.This paper mainly discusses the ore type,chemical composition,mineral composition and the relationship between the content of rare earth elements in bauxite and surrounding rock,It is found that the content of rare earth elements is basically positively correlated with the content of clay minerals,while dolomite and calcite are not conducive to the enrichment of rare earth elements.At the same time,we should increase the research on rare earth elements in aluminous rock series in the province to ensure the rational utilization of resources.
