Process for recovering metal materials from slag

Abstract

A process for recovering (1) metal materials from slag of steel industry and wherein the slag comprises ferrochrome slag (FCS). The slag is heated (2) in a furnace to enhance the extraction of the metal materials from the slag being in molten state. The process further comprises lowering viscosity (3) of the molten slag by adding at least one alkaline material. The slag is also arranged to foam (4) and thereby provide stirring for the molten slag. Further, the metal oxides of the molten slag are reduced (5) by means of at least one reducing agent.
