Treatment process for smelting high-chlorine material by using noble metal

The invention discloses a treatment process for smelting a high-chlorine material by using noble metal. The process is mainly divided into four process stages: (1) concentration stage; (2) an evaporation separation stage; (3) a precious metal recovery stage; and (4) a circulation stage. In the precious metal recovery process, a physical separation method is introduced to separate chlorine and precious metal ions in materials, the problems that under the conditions of high-concentration chloride ions and acidity, the chemical method agent dosage is large, and waste water is difficult to treat are solved, the waste water is effectively treated, harmful chlorine is recovered into recyclable hydrochloric acid, and the waste water is recycled. Moreover, valuable elements which are very low in concentration and even difficult to detect can be recycled, high-grade and easy-to-recycle precious slag is obtained, precious metal is basically not lost, compared with adsorbents such as activated carbon and resin, the tech
