Description
Summary:Results of a system analysis of volumes and physical, chemical, granulometric, lithological, and thermophysical characteristics of waste materials of apatite–nepheline ores stored in tailing dumps of ore mining and processing works are presented to assess the economic viability of using such materials in energy- and resource-efficient and environmentally sustainable processing systems comprised of conveyor belt roasting machines and ore-thermal furnaces. The results allow the formulation of the principal engineering, technological, economic, and environmental requirements imposed on complicated chemical–power-engineering systems for the processing of apatite–nepheline ore waste materials at mining and processing works and the determination of the variability degree of the characteristics of waste batches from different dumps.
