摘要
介绍了国内外稀土资源及竹山庙垭稀土资源状况?通过原矿工艺矿物学研究,查明竹山庙垭稀土矿矿物组成及含量、矿物嵌布特性、稀土在矿石中的赋存状态。通过选冶联合工艺试验研究,获得冶金产品碳酸盐稀土,品位60.46%,总回收率65.43%。
This paper introduced the domestic and foreign rare earth resources and the resource status in Zhushan Miaoya. Through ore process mineralogy study, the mineral composition and content, mineral dissemination characteristics and occurrence state in rare earth ore of Zhushan Miaoya rare earth mine were identified. Simultaneously, through beneficiation-metallurgy combination process experimental study carbonate rare earth of metallurgical product was obtained. The grade was 60. 46%, and the total recovery rate was65.43%.
