Raw materials have a significant influence on the quality of the final refractory products, as the crude ore often comes for processing with significant variations in chemical and mineralogical composition. Therefore, it is necessary to guarantee the stable quality of raw materials with pre-assigned qualitative factors. It is possible to solve these problems by separating raw materials by grades, including the rejection of the portions of material unsuitable for specific application, and by reasonable control of the processing parameters based on real-time information about chemical composition of raw materials. This can be effectively achieved by MAYA laser elemental analyzers based on LIBS. Being applied in extraction, beneficiation and processing of the mineral raw materials, LIBS analyzers can be used for automatic sorting of the ore extracted or crushed and automatic dosage of components to stabilize the composition of raw material mixtures.
