| Abstract: |
| This paper introduced the processing?technology of sulfuric acid mud which is produced in the process of smelting?lead sulphide concentrates with enamel kettle, rotary kiln, and vacuum distillation furnace that can recycle gold, silver, and selenium in the acid mud comprehensively and reuse the resources greatly in Shandong Humon Smelting Co. Ltd. The technology has been successfully applied in production. It is proved that the new process can recycle selenium effectively, concentrate gold and silver in the course of calcination to improve direct recovery of gold and silver, accelerate?cash?flow and improve?the?efficiency?of the?economy. Meanwhile, the process has the advantages of operation simple, low cost and high yield of selenium. |
