一种回收金属硫化矿尾矿中萤石的方法
摘要：
一种回收金属硫化矿尾矿中萤石的方法，涉及一种从多金属硫化矿尾矿选出萤石精矿，特别是从多金属硫化矿尾矿回收低品位萤石的方法。其特征在于其过程的步骤依包括：（1）将金属硫化矿尾矿进行脱泥；（2）磁选除铁；（3）浮选脱硫；（4）粗选得到萤石粗精矿；（5）萤石粗精矿经过磨矿、精选，得到萤石精矿。该方法中旋流器脱泥消除了极细粒泥质矿物对浮选作业的影响，有利于药剂与萤石作用提高萤石回收率；磁选除磁性物质消除了磁性物质对萤石精矿品位的影响，有利于提高萤石品位。解决了含低品位萤石多金属硫化矿尾矿回收的难题。
摘要（英）：

A method for recycling fluorite from a tailing of a metal sulfide ore relates to a method for picking out fine fluorite concentrate from the tailing of a multi-metal sulfide ore, in particular to a method for recycling the low-grade fluorite from the multi-metal sulfide ore. The method is characterized by comprising the following steps: 1, allowing the tailing of the metal sulfide ore to be subjected to mud removal; 2, conducting magnetic separation and iron removal; 3, achieving floatation and desulfuration; 4, obtaining coarse fluorite concentrate through coarse screening; and 5, allowing the coarse fluorite concentrate to be subjected to ore grinding and fine screening, so as to obtain the fine fluorite concentrate. According to the invention, a swirler is used for mud removal, so as to eliminate the influence of the very fine argillaceous ore on the floatation operation and to be conducive to improving the fluorite recovery rate under the action of the medicament and the fluorite; the magnetic material is eliminated through magnetic separation so as to eliminate the influence of the magnetic material on fine fluorite concentrate grade and to be conducive to improving fluorite grade; and the difficult problem of recycling of the multi-metal sulfide ore containing the low-grade fluorite is solved.
