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 electric arc furnace (EAF) slag. The slag is heated (2) in a furnace or fed in molten state to enhance the extraction of the metal materials from the slag being in molten state. Viscosity and / or liquidus temperature (3) of the molten slag is lowered by adding at least one material to alter the acid-base balance of the molten slag. Stirring (4) is provided for the molten slag. Further, the metal oxides of the molten slag are reduced (5) by means of at least one reducing agent.
