Physicochemical Properties and Metallurgical Evaluation of Magnesium—Strontium-Containing Limestones

Abstract

Magnesium—strontium-containing limestones are overburden and lie together with celestite ore, the extraction of which is economically justified under their conditions of use. The results of determination of mineralogical composition of limestone, structural-phase transformations in the production of lime, iron ore agglomerate, and pellets with the introduction of limestone into the charge are given. The viscosity and refining properties of strontium-containing blast-furnace and steel-smelting slags are studied. Magnesium–strontium-containing limestones are a promising fluxing material for the sinter and steelmaking industries.
