    • A process for the production of a PGM-enriched alloy comprising 0 to 60 wt.-% of iron and 20 to 99 wt.-% of one or more PGMs selected from the group consisting of platinum, palladium and rhodium, the process comprising the steps: (1) providing a sulfur-free PGM collector alloy comprising 30 to 95 wt.-% of iron and 2 to 15 wt- % of one or more PGMs selected from the group consisting of platinum, palladium and rhodium, (2) providing a copper- and sulfur-free material capable of forming a slag-like composition when molten, wherein the molten slag-like composition comprises 10 to 30 wt.-% of magnesium oxide and/or calcium oxide and 70 to 90 wt.-% of silicon dioxide, (3) melting the PGM collector alloy and the material capable of forming a slag-like composition when molten in a weight ratio of 1 : 0.75 to 5 within a converter until a multi- or two-phase system of a lower high-density molten mass comprising the molten PGM collector alloy and one or more upper low-density molten masses comprising the molten slag-like composition has formed, (4) contacting an oxidizing gas comprising 0 to 80 vol.-% of inert gas and 20 to 100 vol.-% of oxygen with the lower high-density molten mass obtained in step (3) until it has been converted into a lower high-density molten mass of the PGM-enriched alloy, (5) separating an upper low-density molten slag formed in the course of step (4) from the lower high-density molten mass of the PGM-enriched alloy making use of the difference in density, (6) letting the molten masses separated from one another cool down and solidify, and (7) collecting the solidified PGM-enriched alloy.
    • 一种制备富含PGM的合金的方法,其包含0至60重量%的铁和20至99重量%的选自铂,钯和铑的一种或多种PGM,该方法包括 步骤:(1)提供含有30至95重量%的铁和2至15重量%的选自铂,钯和铑的一种或多种PGM的无硫PGM收集器合金,(2) 提供一种当熔融时能够形成炉渣状组合物的无铜和无硫的材料,其中熔融炉渣样组合物包含10-30重量%的氧化镁和/或氧化钙和70-90重量% %的二氧化硅,(3)在转化器内以1:0.75至5的重量比熔融时熔化PGM收集合金和能够形成炉渣状组合物的材料,直到一个或多个或两相的系统 包含熔融的PGM收集合金和一个或多个上部低密度熔融体的低密度熔融物质组成 点燃熔融的炉渣状组合物,(4)使步骤(2)中获得的较低高密度熔融物质与0〜80体积%的惰性气体和20〜100体积%的氧气接触, 3),直到其被转化为富PGM合金的较低高密度熔融物质,(5)将在步骤(4)中形成的上部低密度熔渣与下部高密度熔融物质 使用密度差的PGM富集合金,(6)使彼此分离的熔融体冷却固化,(7)收集凝固的富含PGM的合金。
