摘　　要：云南锡业公司堆存的锡尾矿粒度细、品位低、锡石结晶粒度极小且大多呈连生体存在，经比较，采用“不磨矿、不脱泥、分级全重选工艺产出富锡中矿再烟化得到锡精矿”的选冶联合流程经济合理。Tin tailings from Yunnan Tin Industry Company is fine in size and low in content.The cassiterite in the tailings with fine crystal size is of intergrowth.Through comparative analysis,the technological process combined dressing and metallurgy is perfectly reasonable in economic significance by which tin concentrate can be obtained from fuming treatment of middlings contained rich tin.The middlings is obtainable from tin tailings through classification and gravity separation no grinding,no desliming.
