Malanchyk Y. Substantion of technology parametrs of complex processing and preparation for the extraction of metals from basalt ram

The object of research is preparation processes including crushing, grinding, classification, separation of basalt raw material, and interaction with the equipment in these processes at complex processing of raw materials. The aim is to determine the dependence of the parameters of the preparation processes of physical and mechanical properties of the metal-basalt raw material, parameters and modes of operation of the process equipment, the development of model representations of their interaction forecast indicators of complex processing and increase the yield of metal industrial products. The subject of the research are based technological parameters for ore preparation operations on the physical and mechanical properties of raw materials and industrial products during parameters variations of mining equipment, which determine the features of the technology of complex processing and preparation for the extraction of metals from raw materials of basalt. Research methods. We used the proven physical and chemical methods of analysis of the elemental, mineral, fraction, particle size distribution of the basalt rock mass, methods of laboratory, semi-industrial and industrial research into the processes of crushing, grinding, classification, electromagnetic separation at the stages of ore preparation of raw materials to produce metal industrial products. Applying the method of statistical modeling and regression analysis of experimental results. Research results: first proposed effective technological solutions for the processes of crushing, classification, magnetic and electrical separation of basalt raw material, which yielded middling and concentrates with a high content of metal minerals. The adequacy of the models tested proved using statistical criteria. Developed technical proposals and feasibility study of the advisability of complex processing of raw materials of basalt, which is confirmed by the novelty of a patent on a method of extraction of tufa, which establishes a regular communication of the results of comparative multicriteria evaluation objects under comparison additive. Practical value: prepared a program of development of mining and metallurgical complex waste-free processing of basalt raw material to produce export-oriented industrial products and concentrates, became part of the program of development of Volyn region; developed technical proposals to improve the conditions of crushing, classification, magnetic and electric separation technology for ore preparation of basalt raw material; Methods for determination of technological parameters of the process integrated waste-free processing of metalliferous basalt raw material; technological schemes of complex processing of raw materials of basalt.
