The article is focused on an approach to mineral processing control using modern technologies—situational control. The keynote idea is the use of formal methods, making it possible to accumulate information on reaching the best results in processing of specific ore grades at a given deposit, and to find standard variables of control actions, which ensured the best processing performance on the same grade ore in the times past. An advantage of the described approach, as against the known solutions on expert systems, is making of reasoned decisions the efficiency of which is confirmed by the earlier case records. The author presents a procedure of transforming vector of characteristics of a control object into a scalar value, which considerably simplifies computation based on enormous databases without the loss of information on the object. The article gives examples of application of the procedure in coding of process grades of ore and in construction of processing control algorithms. A brief review of new automation devices designed by RIVS Science and Production is given.
