Abstract

Halide-containing residues from waste gas purification are, if they have a content of water-soluble constituents, virtually unutilisable and can be put into landfill only with restrictions. As a result of the novel process, the constituents which can be eluted with water are incorporated into a mineral matrix in such a way that a markedly reduced susceptibility to elution is obtained. It also becomes possible to convert the residues into a product which can be used as a hydraulic binder. The halide-containing residues are, as constituents of a raw meal for the manufacture of chlorosilicates, subjected to a thermal treatment.
