The processes of removing highly dispersed suspended solids from process water during the iron ore beneficiation were studied in [6]. The disadvantage of this approach is the use of chemical action on the processes of thickening and desliming, which complicates the operational control of the processes.

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.
