离子型稀土矿稀土储量估算方法对比分析

Comparative Analysis of Estimating Methods for Ion-type Rare Earth Reserves

准确估算离子型稀土矿的稀土储量和品位分布是浸矿剂用量设计和收液工程设计的前提。采用地质储量估算中常用的块段法和克里格法分别估算离子型稀土矿的稀土储量,由于离子型稀土矿探矿工艺易受孤石影响的缺陷,导致块段法的估算结果偏小,而克里格法能较好的估算出矿块的稀土储量和稀土品位分布。因此,建议采用克里格法估算离子型稀土矿的稀土储量和品位分布。

Accurately estimating the rare earth reserves and grade distribution of ion-type rare earth ore is the prerequisite for the design of leaching agent dosage and liquid collection engineering.The block method and Kriging method commonly frequently-used in geological reserve estimation are used to estimate the rare earth reserves of ion-type rare earth ore.Due to the defect that the prospecting process of ion-type rare earth ore is easily affected by boulders,the estimation result of block method is smalller than the actual value.The Kriging method can better estimate the rare earth reserves and grade distribution in the ore block.Therefore,it is recommended to use the Kriging method to estimate the rare earth reserves and grade distribution of ion-type rare earth ore.
