The article describes the main advantages of installation of flotation classification devices in the closed grinding circuit, including fitness of flotation classifiers for work with different products of the grinding circuit even without hydraulic separation, operability in the modes of froth and electric separation and wide range of adjustable parameters that allow adapting the process of flotation classification to almost any type of feed stock. Examples of flotation classification of sulfides, iron ores and tailings in the closed grinding circuit are given. The floatation classifier ensures production of standard quality concentrate in froth product included in the closed grinding circuit of ore processing and maximum extraction of minerals in froth in processing of tailings, with discharge to be dumped. The calculated data on final performance of sulfide copper ore flotation by the developed modeling procedure of flotation regimes with regard to flotation classifier in the closed grinding circuit are presented. These results indicate possibility of increasing copper recovery in concentrate by 4–7 % in the circuit with flotation classification. In general, inclusion of flotation classifiers in the closed grinding circuit helps reduce energy input and improve production data of mineral and waste processing.
