Methodological principles of the selection of a resource-saving technology while developing water-bearing placer deposits

Purpose. The present paper aims to develop methodological principles for the selection of effective parameters resource-saving technologies while developing water-bearing titanium-zirconium deposits basing on complex analytical studies. Methods. applies a research methods: – analyze and generalize main differences development technology placer problem statement; technical-economic analysis identifying effect indices land use open-pit mining involvement associate raw materials in economic activity; forecasting determine influence deposit operating regional nonmetallic material open pits. Findings. Effective trends using located enclosing overburden rocks are identified. Key between from their recovery mineral defined. Predictive extraction building pits is specified. Volumes possible Motronivskyi GZK pit during its operation determined. Originality. New dependences capacity coefficient region, prime cost ore as well number sand clay production region volumes involved Practical implications. A structural-logical scheme elaborated deposits.
