Overview of Magnesia-Carbon refractories bricks waste recycling and reusing from basic steelmaking

Abstract

This paper presents the results of analysis and evaluation of the mechanical, physical and chemical properties of MC refractory brick waste types. From there, it is proposed that these waste treatment methods by mechanical methods, chemical methods, flotation methods to recover MgO as raw materials for the production of MC refractory bricks meet the requirements for use in the metallurgical industry, cement and other industrial equipment. The results of the studies suggest that flotation can be a means of reconciling the quality and cost requirements of recycled MgO aggregates.
