Abstract

Technological advance of a mine with regard to ecological and economic evaluation takes shape as a generalized model of activities aimed at higher profit return, increased extraction of mineral resources from the subsoil, cut-down cost of mining and processing, and at reduced waste and harmful emission. The authors assess the open pit mining efficiency as a function of concentrate production cost as a case-study of Pokrovsky GOK, Ukraine. Statistical correlation of the production technology and economy and the produced ore flow quality is determined. A blending procedure is proposed for manganese ore from two groups of open pits to ensure the largest extractability of the useful component at the minimum cost of stripping. Preset quality ore should be accumulated at a processing plant for the concentrate production, with follow-on re-adjustment of the process circuits to ore with another content of metal. Free market economy has a material effect on production performance in the mining and processing industry, first of all, on the volume of products sold.

Keywords: open pit, manganese ore, ore flow quality, technology and economy efficiency, metal recovery, concentrate cost
