本文通过化学分析、AXIOS型半定量分析仪分析检测,对寻乌某风化壳淋积型稀土矿含量及成矿原理进行研究。首先采用草酸重量分析法测定矿物中离子型稀土的含量,然后再通过AXIOS型半定量分析仪测得矿中总的稀土含量。研究结果表明寻乌某风化壳淋积型稀土中离子型稀土的含量占该矿总稀土含量的76.42%,说明寻乌某风化壳淋积型稀土主要以离子型稀土存在。这对矿物中稀土的提炼及成矿原理机理具有指导性意义。
In this paper, through chemical analysis, AXIOS semi-quantitative analyzer analysis and detection, we studied the mineralization and the ore-forming mechanism of a weathered crust-type rare earth deposit in Xunwu. Firstly, the content of ionic rare earth in mineral was determined by oxalic acid gravimetric analysis, and then the total rare earth content in the ore was measured by AXIOS semi-quantitative analyzer. The results show that the content of ionic rare earth in the weathered rare earth in Xunwu arsenic accounts for 76.42% of the total rare earth in the ore, indicating that the leaching rare earth in the weathered crust of Xunwu mainly exists as ionic rare earth. This is of guiding significance for the extraction of rare earths and the mechanism of mineralization in minerals.
