High Efficient Enrichment and Activated Dissolution of Refractory Low Grade Rh-containing Material

摘要：

Aiming to the low-grade rhodium-containing waste materials, a new process was proposed to enrich and activate rhodium by smelting using iron oxide as a trapping agent and activator. A rhodium concentrate was obtained by the separation of base metals and precious metals. The concentrate was reacted with dilute aqua regia to obtain rhodium solution. The factors influencing the enrichment and activation effects were discussed in this paper. The results showed that the dissolution rate is greater than 99％ under the optimum conditions. In this process, the activation of rhodium was finished in the enrichment process. The iron oxide is both a trapping agent and activator, which simplifies the process and reduce the cost.
