Abstract

Dans un procédé de récupération de PGM et de ferrochrome à partir de minerais de chromite porteurs de métaux du groupe du platine, on prépare un concentré qui contient la plupart des PGM et la chromite du minerai et le concentré est soumis à une étape de chauffage afin de le sécher et/ou le préchauffer le concentré, après quoi le concentré préchauffé est fondu sous des conditions réductrices dans un four de traitement de minerais (14) pour produire un alliage métallique fondu contenant les PGM de l'alimentation et le laitier fondu contenant le chrome de l'alimentation. Le laitier fondu est versé du four de traitement de minerais (14) dans le four à fondre les scories AC (16) où le fer et le chrome sont réduits pour produire un alliage de ferrochrome. Les PGM sont récupérés de l'alliage métallique versé du four de traitement de minerais (14) en utilisant des procédés hydrométallurgiques.
