Abstract

Relevance. Currently, one of the most important areas in the Russian mining industry is gold mining, whose significant part is attributed to placer deposits (26-31%) [1]. The structure and quality of placer gold reserves are deteriorating, and the role of technology-related formations is growing. Over the long years of exploitation of placer deposits, a large number of dumps have been accumulated as a result of sand washing; some of them can be profitably processed [2-8]. It should be noted that literature gives extremely little focus on the problem of profitable development of low-productive placers, and there are opinions that such placers cannot be considered as significant sources of gold mining even at the present stage [9]. Objectives. The paper deals with the problem of bringing productive dumps into opera-tion, and the solution is aimed primarily at the cost-effective development of the reserves of this group. Research methods. Analysis and comparison of the most common methods for the development of placer deposits and assess-ment of their suitability for the involvement in the operation of dumps, taking into account feasible subsoil use, eco-nomic efficiency and reducing the negative impact on the environment. Results. The paper analyzes efficiency of existing methods for the development of placer deposits in the context of their suitability for the cost-effective development of dumps. The authors presented solutions that contribute to reasonable and cost-effective involvement of this group of reserves in the development. The paper presents recommendations for the improvement of mining equipment. Conclusions. At the present stage of placer gold mining in Russia, deposits with low quality reserves can be involved in the development, factoring into the presented available work experience, and acceptable process flow charts with the calculation of the approximate economic effect.
