Разработка технических решений по повышению надёжности и долговечности двигателей и движителей ходового оборудования горных машин
This document is a master's thesis focusing on the development of technology for processing sulfide gold-arsenic ores and concentrates under the conditions of the GMZ-3 plant in Uzbekistan. It covers topics such as the analysis of existing literature, mineralogical studies of ores, flotation regime optimization, oxidative roasting, economic aspects, and safety measures.
Asosiy mavzular
- Analiticheskiy obzor literatury (Literature Review): This section reviews existing literature related to gold ore formation, processing technologies for sulfide gold-arsenic concentrates (including roasting and bio-leaching), methods of gold extraction and processing, and the environmental impact of these processes.
- Mineralogicheskiye issledovaniya rudy mestorozhdeniya Kokpatas i Daugiztau (Mineralogical Studies): This section focuses on the mineralogical composition of ores from the Kokpatas and Daugiztau deposits in Uzbekistan, with a specific emphasis on the form and size of gold found within sulfide minerals (pyrite and arsenopyrite).
- Issledovaniya po opredeleniyu optimal'nogo rezhima flotatsii rudy (Flotation Regime Optimization): This section details research conducted to determine the optimal conditions for the flotation of gold ores from Kokpatas and Daugiztau using both traditional and locally sourced reagents. It examines reagent types and dosages for improved gold extraction.
