摘　　要：介绍了减压蒸馏脱硫，熔炼富集，高温悬浮氯气浸出处理热滤渣的工艺。其综合利用好，元素硫脱除率＞９２％，贱金属浸出率＞９５％，贵金属回收率＞９９％。贵金属富集物可并入贵金属精炼分离工段处理。A new process for extracting valuable metals and recovering sulphur from hot filtrating cake by depressurizing distillation desulfurizing,smelting concentration,and high temperature suspend chlorine leaching has been introduced.The separation of element sul fur can be up to above 92% and the leaching effecience of base metals can also be up to above 95%,Above 99% of precious metals can be recovered by the process.Concentra tions of precious metals obtained can be treated by refining process to get pure metals.
