CA 2699517

In the process of recovering platinum group metals from platinum group metal-and base metal-containing materials, the present invention uses reductants and a sulfur- deficient matte to aide the separation of the furnace matte from the furnace slag and therefore improve recovery of platinum group metals.

La présente invention concerne un procédé de récupération de métaux du groupe du platine à partir de matériaux contenant un métal de base et un métal du groupe du platine. Ledit procédé utilise des agents réducteurs et une matte à teneur réduite en soufre afin de faciliter la séparation de la matte de four du mâchefer et d'améliorer ainsi la récupération des métaux du groupe du platine.
