One of the most promising classes of mathematical models of production processes of complex structure, such as production processes of mineral processing, are structural models represented by systems of nonlinear equations ...

Despite the large number of works devoted to models of single-stage nickel grinding, there is no model reflecting the relationship between the main grinding parameters and the classifier discharge fineness ...

The task of full automation of the process of flotation of apatite-nepheline ores turns out to be very difficult for a number of reasons. ...

The economic performance of the enterprise and a significant part of the current constraints, of course, are not absolute and depend on the tasks solved by the national economy as a whole. Their influence is manifested, first of all, through the pricing system, a given plan of conditions of financing, sales of products and material and technical supply...

The use of local systems of automatic control of the flotation process will be effective only with scientifically substantiated schemes and principles developed for a particular technological mode and equipment. In-depth study of the influence of various factors on the technological characteristics of the process is absolutely necessary. It is desirable to have a sufficient number of easily controllable factors that have a comprehensive impact on the technological performance of the process. Such factors include the cost of reagents, the amount of pulp entering the flotation, the level of pulp in the chambers of flotation machines, the pH of the pulp and its temperature.
