Article

On the basis of studying the chemical and mineral compositions, microstructure and properties of self-disintegrating ferrochrome aluminothermal slag a fundamentally new highly effective waste-free technology has been developed for preparing fuzed alloyed spinel Mg(Al, Cr)2O4. The test slag exhibits binding properties. After spinel extraction its limestone-silicate-aluminate component may be used for producing more than ten forms of product: cement, pigments, building and other materials.
