A Short Review on Utilization of Ferrochromium Slag

ABSTRACT

The ferrochromium slag is an important by-product of ferrochromium industries. Recycling and efficient utilization of the large volumes of slag generated by ferrochrome production process is a huge challenge for ferrochrome producers. This article reviews ferrochromium slag utilization with reference to refractory, ceramics and construction and other applications. In addition to this the development of crystal phases and the environmental aspects of ferrochromium slag in relation to its utilization are discussed. The crystalline phases evolve during solidification impart unique properties like strength, stability and refractoriness which open its opportunities as an alternative raw material for ceramic, refractory, civil construction. Chemical composition of ferrochromium slag can be altered suitably for application in high temperature refractory ceramic application. The use of ferrochromium slag in building and road making material will relieve some of the burden from natural resources.
