总结了等离子熔炼技术在贵金属二次资源回收领域的工业应用情况，介绍了等离子熔炼工艺流程和等离子熔炼尾气的处理过程，并对铁捕集铂族金属的原理进行了初步分析。通过一定规模的工业试验得到了等离子熔炼铁捕集技术从二次资源物料中富集铂族金属的初步工艺条件，铂、钯的回收率达到98%，铑的回收率达到97%以上，证明了等离子熔炼铁捕集技术富集铂族金属具有环境友好、铂族金属回收率高、物料适应性广等优点。
Plasma melting technology in the industrial application field of precious metals recycling from secondary resource are summarized, the process flow of plasma melting and the process of plasma melting tail gas treatment are introduced, and the principle of iron capture platinum group metals are preliminary analyzed. Through industrial test of a certain scale has got the preliminary process conditions for plasma melting iron capture technology from secondary resources material enriching of platinum group metals, the recovery rate of platinum, palladium reached 98%, rhodium over 97%. It has proved that the plasma melting iron enrichment platinum group metal capture technology has advantages with environmentally friendly, higher platinum group metals recovery rate, and wide adaptability, etc.
