| titleOfInvention | Process for the production of PGM-rich alloys |
| abstract | A process for producing a PGM-rich alloy comprising 0 to 60% by weight of iron and 20 to 99% by weight of at least one PGM selected from the group consisting of platinum, palladium, and rhodium, the process comprising: , (1) 30 to 95% by weight of iron, less than 1% by weight of sulfur, and 2 to 15% by weight of one or more PGMs, PGM comprising at least one PGM selected from the group consisting of platinum, palladium, and rhodium. Providing a PGM collector alloy; (2) Providing a copper- and sulfur-free material capable of forming a slag-like composition upon melting, wherein the molten slag-like composition comprises 40 to 90% by weight of magnesium oxide and/ Or calcium oxide and 10 to 60% by weight of silicon dioxide; (3) In the converter, the PGM collector alloy, until at least one higher low-density molten mass multi-phase system or two-phase system comprising the lower high-density molten mass and molten slag-like composition comprising the molten PGM collector alloy is formed. And melting a material capable of forming a slag-like composition upon melting in a weight ratio of 1:0.2 to 1; (4) oxidizing gas containing 0 to 80% by volume of inert gas and 20 to 100% by volume of oxygen and the lower high density melted mass obtained in step (3) until converted to the lower high density melt mass of the PGM-rich alloy. Contacting; (5) separating the upper low-density molten slag formed in the process of step (4) from the lower high-density molten mass of the PGM-rich alloy using the difference in density; (6) allowing the molten masses separated from each other to cool and solidify; (7) collecting the solidified PGM-rich alloy. |
