description: The subject of the graduate qualification work is Â«Development of technology for autoclave oxidation of molybdenum-containing sulfide materialsÂ». This work is devoted to the study of separate and joint oxidative autoclave leaching of synthetic sulfide molybdenum products and concentrates of enrichment of sulfide molybdenum raw materials, as well as the development of technology for the autoclave oxidation of molybdenum-containing sulfide materials. During the study, the following tasks were solved: The study of literature data with the compilation of a review of methods for processing molybdenum-containing sulfide materials and intermediate products with a detailed consideration of hydrometallurgical technologies for its decomposition. Tests on oxidative autoclave leaching of molybdenum-containing sulfide materials and ammonia leaching of the autoclave leaching residue. Processing the results of the experimental part providing design criteria for the oxidative autoclave leaching technology of molybdenum-containing sulfide materials. Development of technology for autoclave oxidation of molybdenum-containing sulfide materials. Experimental work was carried out based on the Nietz Technologies laboratories complex, where experiments were perform on autoclave oxidation, ammonia leaching, measurement of the particle size distribution of various, as well as chemical analyzes of liquid and solid phases. A thermodynamic assessment was given for the main reactions occurring in the oxidative autoclave leaching process. The calculation was carried out using the Fact Sage and HSC Chemistry software, equipped with databases of the necessary thermodynamic parameters.The paper contains conclusions on every chapter and a general conclusion on the work. The conclusion contains an analysis of the results of experiments, consequences, proposals for future work. Schemes of technology for processing various molybdenum-containing sulfide materials have been developed based on the results of laboratory work.
