Evaluation of the Potential and Technology for Development of Deposits of Copper-Pyrites Ores in the Circumpolar Ural Zone

Resumo

On the basis of geological assessment of reserves of copper ore in the territory of the Khanty-Mansiisk Autonomous Okrug–Ugra possibilities are considered for developing potential pyrite ore regions considered to be priority for development of pyrite copper-zinc ores. The volumes of primary ore extraction are proved, and the main approaches to developing deposits, parameters of priority quarries and the composition of the main technological and processing equipment are determined. Approaches and a fundamental qualitative-quantitative scheme are developed for pre-concentration of ore using dry methods for pre-enrichment whose implementation will make it possible to minimize adverse environmental impact on the Circumpolar Ural environment. A production scheme is developed for the chain of concentrating processing mining and processing plant devices for treating copper ore. Volumes of raw material and intermediate concentrate processing are determined that ensure the economic effective development.
