A great number of various factors to a different extent impact iron ore treatment, properties of mineral composition of ore and parameters of technological equipment being some of them. To solve the problem of improving performance of a concentration plant in terms of the concentrate, it is required to elaborate effective scheduled procedures, upgrade technological equipment, develop methods of control over concentration processes considering technological properties of ore fed. There is suggested a method of improving efficiency of magnetic concentration of iron ore under the action of high-intensity ultrasound. There are established dependencies between physical-mechanical and chemical-mineralogical characteristics of iron ore slurry solids and their behavior in technological flows under controlled ultrasonic vibrations, this enabling simulation modelling of the process and specification of optimal controlling actions. The research object is assessment of characteristics and control of iron ore magnetic concentration on the technological line of the ore concentration plant. The research subject is the cyber-physical system based on using impacts of highintensity ultrasound on slurry solids to assess characteristics of iron ore magnetic concentration. Obtained dependencies and mathematical models of the non-linear spatial process of high-intensity ultrasound propagation in the iron ore slurry enable implementing the method of assessing characteristics of iron ore magnetic concentration and due to this increase efficiency of the mentioned operations. There are suggested methods of calculating intensity of high-intensity ultrasound in a certain point of the measurement area in order to perform forecast displacement of ground ore particles and changes of the fraction composition of slurry solids under the controlled action of high-intensity ultrasonic vibrations. The developed method and the software-engineering complex for its implementation enable restoring a function of distributing ground ore particles by sizes, forecasting results of technological operations and forming controlling actions.

Bulk raw materials handling plant and sintering plant preparatory plants are established to receive, blend, stockpile, prepare and supply specified grades of raw materials for smooth operations of iron making plant (Blast furnace), steel making plant (Basic oxygen converter) and lime Plant(calcinations plant). The study discusses bulk raw materials handling and some general problem of scientific analysis and documentation of basic equipment details, stockyard facilities, bulk materials transport systems and sinter processes, for the general knowledge and operational procedures of these plant for effective and efficient operational processes for optical results. Iron ore concentrate supplied from the mines to some extent fluctuate in their chemical composition as a result of the nature of the deposit with various factors controlling beneficiation processes and addition of metal-bearing materials collected as a waste product from the Rolling Mills, Blast Furnace and Sinter Plant which must be recycled through Iron ore concentrate stockyard. The part of the sinter mixture is melted at a temperature about 1300-1480 ° C and a sequence of reactions shaping the sinter cake to be loaded into the blast furnace to produce iron from a pig.
