摘要
介绍矿石中伴有少量的砷影响矿石中铅锌的浮选,该方法与其它测定方法比较,具有方便、快捷、节省物力人力及对环境污染少等优点,能够满足多种矿物中砷测定要求,实验结果表明,重铬酸钾容量法能准确测量铅锌矿石中砷含量,样品回收率可达97.4~101.3,对选矿工艺有重要的指导意义。
The amount of arsenic in ore with zinc ore flotation effect, compared with other methods this method is convenient and fast, saving manpower and less environmental pollution etc. it can meet various requirements for the determination of arsenic in minerals, the experimental results show that the potassium dichromate volumetric method can accurately measure the content of arsenic lead-zinc ore in the sample, the recovery rate can reach 97.4~101.3, has an important significance for the beneficiation process.
