| 中文摘要: |
| 铑价格昂贵，在现代工业中发挥着重要作用，冶金原料包括矿产铂族金属精矿和废催化剂、废合金等二次资源。本文针对贵金属生产过程中含铑冶金原料的浸出工艺进行了介绍。不同原料需选择不同的浸出方法，包含水溶液氯化法、王水溶解法、氧化酸浸法和电化学溶解法等。浸出前的预处理方式包含合金化(金属捕集)、钠盐熔融和中温氯化等。随着含铑原料处理规模的增大，开发节能低耗、经济高效、绿色环保的浸出工艺是未来的重要发展方向。 |
| 英文摘要: |
| Rhodium is expensive and plays an important role in modern industry. Its metallurgical materials include mineral platinum-group concentrates and secondary resources such as spent catalysts and spent alloys. This article introduces the leaching method of rhodium-containing metallurgical material in the refining process of precious metals. Different leaching methods apply to different materials. These methods are aqueous chlorination, aqua regia dissolution, oxidizing and electrochemical dissolution. The pre-treatment process before leaching includes alloying (metal trapping), sodium salt melting and medium temperature chlorination, etc. With the increase in the processing scale of rhodium-containing raw materials, the development of energy-saving, low-consumption, cost-effective, and green leaching processes is an important direction in the future. |
