Location: Krasnoyarsk territory, Russian Federation.
Year of implementation: 2024.
Project objective: Comparison of economic indicators of processing lead concentrates of a given composition produced by the Novoangarsk dressing plant to obtain commercial metallic lead, the quality of which must meet the requirements of GOST 3778-98 for grades C0 or C1C, according to pyrometallurgical and hydrometallurgical process flow charts.
A special feature of the project was that, unlike pyrometallurgical production methods, which are based on many years of practical experience and are widely developed in the world, hydrometallurgical ones are used at best on a pilot scale, and in most cases - at the stage of laboratory development. To find the optimal hydrometallurgical flow chart, research work was carried out, including laboratory tests.
Result of the work: Technical report with a description of technological processes, including calculation and selection of main and auxiliary production facilities, equipment, solutions to environmental issues and drawings with diagrams and a master plan of the sites, which in turn served as the basis for the preparation of a technical and economic calculation and a financial and economic model for each option.
