Abstract
Problem Statement (Relevance): This article describes the capabilities of an advanced complex of mineralogical analysis methods applied for studying the technical stone. With the help of the complex, one can obtain complete and reliable information on the material composition and the morphostructure of the mineral phases, simulate the mineral formation processes behind the technical stone, analyse the economic needs of the region and predict what areas the technical raw materials are likely to find further application in. Using the example of the blast furnace slag, the authors support the feasibility of integrating the conventional mineralogical methods (such as optical microscopy and quantitative X-ray analysis) with the methods of electron microscopy and X-ray spectroscopy. Objectives: This research aims to substantiate the feasibility of integrating mineralogical analysis methods for studying metallurgical slags. Methods Applied: A combination of advanced mineralogical analysis methods including optical microscopy (optical petrography and mineralogy), quantitative X-ray analysis, electron microscopy and X-ray spectroscopy. Mineralogical studies are regulated by the guidelines approved by the Council for Mineralogical Research Methods. Originality: The originality of this research is in the novel approach to studying the material composition of slags, i.e. using a combination of the mineralogical analysis methods. Findings: This article describes the results of the study into blast furnace slags. Due to the optimum combination of methods, the authors were able to carry out a phase analysis of the slags, determine the actual chemical composition of the phases identified and the distribution of the chemical components across the grain plane, study the morphology of the slag-forming mineral phases and their spatial relationships. All that helped identify the sequence and the mechanism of phase formation. Practical Relevance: The data obtained provide all the information about the phase composition of the slags in view, as well as the mechanism of how the slags form in the blast furnace hearth.
