摘　　要：针对湖南某地含砷废渣的特点,在查明了渣样矿物性质以及镶嵌关系和赋存状态的基础上,进行了磨矿细度的回收条件试验,在-0.2 mm的磨矿细度下采用磁选-摇床工艺流程处理砷渣,可获得铁精矿和锡精矿;工艺废水采用石灰法处理,可达到国家规定的排放标准。On the basic of understanding the characteristics of the arsenic waste in Hunan, we learned the mosaic relationship and the modes of occurrence about residue of mineral properties. Moreover, we did the arsenic waste processing, which shows as the optimun grinding fineness is -0.2 mm, and using a benefieiation technology of high intensity magnetic separation and tabling, Iron ore and Tin concentrate can be obtained by the recovery con- dition experiment of grinding fineness, and the wastewater after treatment by lime process reached the standard of the national discharge.
