The problems of assessing the economic efficiency of production of each of the valuable components of mineral raw materials at its complex processing are considered. The disadvantages of the traditional approach based on the condition of recoupment of the full cost of the evaluated component (the sum of direct and the corresponding part of indirect costs) are revealed. The estimation methodology is proposed, which provides compensation of only direct costs for any valuable component separately and payback of the sum of direct and indirect costs of extraction and multi-product processing of raw materials.
