Abstract

Purpose. Extraction and processing of iron ore is impossible without control of the content of magnetite iron at all stages. Timely and reliable information about the physicochemical properties of iron ore is necessary to control the process of its processing. The methods and tools currently used limit industrialists in the amount of measurements taken, the time required to obtain measurement results and the accuracy of their implementation, which in turn affects the quality and cost of final products, and increase losses. Research methods. A complex research method was used: analysis of physicochemical composition of iron ores, theoretical generalizations using the theory of interaction of electromagnetic fields with rocks, methods of mathematical, simulation, computer and field modeling. Theoretical and practical methods of planning experiments, mathematical processing, analysis of results. Theories of mining, electrical engineering, algorithms and control are used in the work; methods of numerical, statistical analysis and probability theory were used to process and generalize the obtained data. Scientific novelty. The analysis and classification of methods of quantitative analysis of magnetite iron is carried out. For further work, the inductive method was chosen as the most promising. A model of an autogenerator magnetometric transducer for determining the content of magnetite iron is proposed. The high accuracy of the method and the model that implements it on iron ore samples is proved. Practical significance. The use of the proposed autogenerator magnetometric transducer in the means of operational quality control of iron ores will increase the accuracy of measuring devices of operational control by reducing the instrumental error. Results. Among the considered methods of quantitative analysis of magnetite ores selected inductive, as the most promising, accurate, operational, easy to implement measuring instruments. A model of an autogenerator magnetometric measuring instrument that implements the inductive method is proposed, laboratory studies have determined its accuracy
