| 摘 要： | 针对氧化铜锡矿嵌布粒度细、共生关系复杂的技术难题，对塔吉克某氧化铜锡矿进行了选矿实验研究. 结果表明，该矿中铜品位为0.89%，锡品位为0.87%，铜氧化率接近100%，锡主要以锡石形式存在. 经多个实验对比分析，最终采用硫化-黄药法回收铜、法尔肯加摇床分级重选法回收锡的选矿流程. 通过闭路实验，得到铜品位15.26%、回收率85.90%的铜精矿及锡品位52.57%、回收率71.30%的锡精矿.

| Abstract: | Tajik copper-tin oxide ore was studied for the technological problems of fine mineral dissemination and complex intergrowth. The results showed that the grade of copper in original ore was 0.89% and tin 0.87%. The oxidation rate of copper was up to 100% and cassiterite existed mainly in the form of tin. After comparison of multiple experiment trials, the processes of sulfuration-xanthate to recover copper and Falcon shaking table to recover tin were ultimately used. By the closed circuit flow experiments, the grade of copper concentrate obtained was 15.26% with the recovery rate of 85.90%, and the grade of tin concentrate 52.57% with the recovery rate of 71.30%. |
