| titleOfInvention | A method for cascade recovery of rare and precious metals in selenium distillation slag |
| abstract | The invention discloses a method for cascade recovery of rare and precious metals in selenium steaming slag. Hydrazine immersion silver. The present invention can destroy selenium, tellurium and copper, gold, silver, etc. in the selenium steaming slag to form interchemical compounds and inclusion structures through alkaline oxidation roasting destruction, realize the stepwise selective recovery of rare and precious metals, and the comprehensive recovery rate of rare and precious metals is high. It is simple and low in production cost, and the products obtained after the separation of each process can be grafted with the original rare and precious metal treatment process of the enterprise, which makes up for the lack of the current selenium steaming slag treatment process, and is easy to be popularized and applied on a large scale. |
