ABSTRACT:
The invention relates to a method and compositions for modifying the physical and/or chemical characteristics of metallurgical slags and cinders by injection into the latter, during pouring in the molten state, between the ladle and the cooling pit. These compositions are mixtures of carbonate products and free carbon products in the form of wastes and residues such as mining or quarry sterile materials and blast furnace gas dusts. The injection can be effected in the presence of a support such as fine particle steel mill slag or sodium slags from pig iron desulfuration. The process is applicable to the treatment of type LD steel mill slags and phosphate slags designed for agriculture.
