Mill scale recycling is also being done by briquetting it after mixing with a binder. Mill scale is also used as a raw material in granular refractory. When this refractory is cast and preheated, mill scale provides escape route for the evaporating water vapour, thus preventing cracks and resulting in a strong monolithic structure.
