Justification of an approach to an economic assessment of projects development of technogenic mineral objects

Abstract

With the gradual reduction of the quality of mineral resources and the deterioration of mining and geological conditions of mining operations there is a need to revitalize the mining companies withing the Russian Federation to engage in the processing of the existing technogenic resources. This problem is particularly relevant for the Northern regions, where a significant amount of mining waste has accumulated as a result of long-term mining. This involves increasing the investment attractiveness of the waste management of mining projects through the development of methodologies for the economic evaluation of projects. The purpose of this research is to develop a methodological approach for economic evaluations during the development process of technogenic mineral processing facilities and mining waste projects.The considered research methods include: justification of key elements of the evaluation of project developments and technological fields of waste processing, compare the types of projects, the rationale for the selection of project solutions to the socio-environmental projects and organizational results.The study results propose a methodology for deciding on the implementation of development projects of technogenic deposits and recycling, based on the flexible use of the criterion of net present value (NPV) to evaluate the effectiveness of the project.
