Improvement of technologies and technical means for ore mining and processing industry
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 4
Abstract
Objective is improvement of technologies and technical means for mining and processing industry on the basis of taking into account of functional subsystems, as well as their purpose and the main characteristics of the automated system when ore processing. Methodology consists in analysis of literature sources, methods of theoretical generalizations of physical properties of ores, device development, physical and mathematical modeling, as well as laboratory research and industrial implementation using conventional and standard techniques. The main scientific and practical results of improvement of technologies and technical means for mining-and-concentrating industry are shown using the example of deposits with a complex structure which have been developed by experts of the industry and leading scientific centers of the Russian Federation, Ukraine, Kazakhstan, and other CIS countries. The modern mineral and raw materials base of CJSC Vasilievsky Rudnik and main organizational and technological measures to increase its efficiency for the base of some companies are described. The issues of concentrating and processing of extracted gold ores, organizational measures for CJSC Vasilievsky Rudnik (Russian Federation) aimed at increasing the efficiency of production at these process stages are considered. Scientific novelty. A new system of head sampling at the gold recovery plant was developed and introduced, which allowed improving sharply the reliability of the results, reduce labor costs and decrease of the number of samples processing by the laboratory from this operation by 6 times. Practical significance. Measures increasing the efficiency of the gold recovery plant, technological sampling maps, new designs of crushers and mills, which allowed us to increase the efficiency of crushing and grinding of open grains of gangue depending on the deposits of useful minerals were proposed. The results of preliminary studies on the concentration of oxidized quartzites (Krivbass, Krivoy Rog, Ukraine) have shown the possibility of obtaining concentrates with a mass fraction of iron to 60.6% with a recovery level of 76.9%. The mass fraction of iron in the tailings is 14.
