摘要：The environmental problems caused by refractories have became an increasingly important issue inrecent years. The disposal of spent refractory materials has become a major problem for metals producers. The mainissue of refractory disposal is elimination of the hazardous components of refractories, most commonly bauxite,copper, magnesite and chrome-bearing materials in cement industries. The various approaches to pollution preventioninvolve re-design to eliminate or significant reduction in wastes, recycling or reuse of the materials, and the leastvaluable approach, abatement. The objectives of this research are to recycle and reuse of used refractory materialoptimized by porosity, service temperature for low duty process to save the rebuild costs, energy, resources and globalenvironment. Samples from different types of refractory linings were characterized to determine and predict possiblemetal penetration. Crushing and grinding were used to liberate brass through the formation of strips which could beseparated from the crushed refractory by screening. A refractory mix was developed to recycle the remaining crushedrefractory size fractions by mixing with virgin refractory materials for manufacturing low duty refractory castables forfurnace backup and refractory mortar. An assessment study of spent refractory materials on application is studied.
