[0002] In the traditional platinum group metal recovery process, the main reliance is on pyrometallurgical roasting enrichment technology. Although this method can effectively recover precious metals, it has many shortcomings. First, the process requires the addition of a large amount of slag-forming agents and fluxes, which will produce a large amount of waste slag during the smelting process, causing secondary pollution to the environment. Secondly, the smoke and harmful gases generated during the traditional roasting process are not environmentally friendly, and there is an urgent need to adopt more environmentally friendly technologies to reduce the impact on the environment.
