  • WO2005031013A1 Platinum group metal extraction by ore

    A process for extraction of platinum group metals (PGM) includes smelting PGM concentrate to provide PGM-containing matte, spinel-rich slag and oxide-rich slag. The matte is enriched with regard to PGM in a conversion step by selective oxidation of undesired constituents thereof. The process includes, after the smelting and prior to the conversion, separating the matte and the spinel-rich slag

  • Pyrometallurgical upgrading of PGM-rich leach residues

    The production of Platinum Group Metals (PGM) normally entails the smelting of PGM flotation concentrates, converting of the furnace matte and removal of the bulk of the Ni, Cu, Co, S and Fe through atmospheric and pressure leaching in a base metals refinery to produce a PGM-rich concentrate.

  • Converter Slag Flotation—its Effect on Copper

    The Naoshima Smelter has employed the convert er slag flotation method in order to increase reverberatory smelting capacity instead of returning slag to the reverberatory furnace. As the result, we could point out the following advantages; 1) Copper anode produced from copper concentrate was increased 25%, from 3,000T/M to 3,800T/M. 2) Magnetite trouble in the furnace was decreased. 3)

  • Recovery of Copper from Slow Cooled Ausmelt Furnace Slag

    Ausmelt furnace slag contains about 0.9% Cu (mass %). With increasing the amount of Ausmelt furnace slag, the recovery of copper from it will produce an enormous economic yield. The recovery of copper by floatation from slow cooled Ausmelt furnace slag was studied in this paper. The phases and composition of the slow cooled slag were analyzed.
