The ore pretreatment process is based on suitable comminution of feed in order to liberate the useful minerals from ore. Industrial comminution is the most energy-consuming process in the entire concentration flowsheet which determines the obtained overall technological effects. The properly designed comminution circuit is therefore of crucial importance from the point of view of the economics of the concentrator. The suitably designed system is grounded on modern comminuting devices, particularly on high-pressure grinding rolls (HPGR). Together with the examination of the comminution circuit from the point of view of devices selection, the authors give a key-role to the feed characteristics issues, because these both aspects are the basis of the selection of the comminuting circuit ready to carry out the technological task. The authors take into consideration all possible aspects of a modern approach to modeling and optimization of mineral raw materials comminution flowsheets in order to maximize the technological (desired quality of the product), energy (reduction of energy-consuming-of the process) and environmental (optimal utilization of the raw material) effects.
