Recycling Practices of Spent MgO-C Refractories
recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming slag conditioner because of their MgO content. Crushed MgO-C spent refractories can be reused directly back into an EAF without complex and costly beneficiation.

Final Report SummaryREFRASORT (Innovative Separation
Recycling of spent refractories could constitute an important new secondary source of refractory raw materials. It is estimated that up to 20 of raw material demand could be met by secondary resources. But although recycling of refractories has increased significantly in Europe in the last decades it has still far from reached this target.
