XRF测定铅锌矿选矿流程中铅、锌、铜

DETERMINATION OF Pb, Zn, Cu IN PROCESSING LEAD-ZINC MINERAL BY XRF

本文叙述一个ＸＲＦ粉末法测定铅锌矿选矿流程中铅、锌、铜的方法。选用精、中矿和原、尾矿两个标准系列。ＲｈＫα康普顿散射线作内标克服质量吸收系数变化带来的影响，用经验系数法校正基体效应。与化学分析方法相比，本法具有测定组分含量范围广、简便、快速、准确和成本低等特点。配合选矿试验大大加快选矿周期。

Pb, Zn, Cu in processing lead-zinc mineral were measured by XRF using pelletigzed powder samples. Two series of standard samples were prepared. The RhKαcomp ton scattering line was used as internal standard and matrix effects were corrected by empirical coefficient method. The direct determination method offers large determination range, and accurate, rapid, simple and cheap features as compared with chemical method.
