ABSTRACT:
A method of obtaining glass materials from ash-slag. Waste wherein the waste is heated to a melting point temperature and melted in a reducing medium. The obtained melt is cooled by a thermal shock to form a foamed glass material. Prior to heating the charge, the carbon content therein is brought to 3.0-8.0 wt %, and the foamed glass material is foamed under a flow of a gaseous medium resulting form decomposition of carbides formed in the melt as a result of carbon content adjustment. Carbon addition also reduces iron oxide present in the waste, this reduction facilitating iron separation from the foamed material.
