ABSTRACT OF THE DISCLOSURE Molten metallurgical slags are expanded by contact with water in a liquid or vapor state by passing the molten slag along a prefoaming or expanding through by delivering the slag to this trough via an intermediate trough which is shift- able along the prefoaming trough in order to vary the location at which the slag contacts the prefoaming trough and the expend- ing-agent film thereon in accordance with physical characteris- tics of the molten slag, especially its temperature and visco- sity. From the pre-expanding or prefoaming trough, the par- tially expanded slag may be subjected to expansion by conven- tional means, e.g. a rotating drum which disperses the slag particles trough the air so that they can be collected in a completely expanded, dry and solidified state.
