1. Introduction. Comminution of the ore can take up to 3050% of the total operating costs of mining (Aldrich, 2013, Jeswiet and Szekeres, 2016).The most energy intensive process in the comminution is grinding, for which the operation cost increases with the fineness of the product (Wang and Forssberg, 2007, Jeswiet and Szekeres, 2016).Generally wet grinding is favoured over dry grinding ...

Iron ore is an important raw material for steel production enterprises. In most cases, iron ore with a grade of less than 50% requires ore beneficiation before smelting and utilization. Natural ore (iron ore) is gradually selected for iron through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation.
