Iron ore beneficiation technologies in Russia and ways to improve
DOI: 10.31897/PMI.2022.61 Increasing the efficiency of crushing circuits is associated with a decrease in the particle size of finely crushed ore and the use of dry magnetic separation of crushed ore. Reducing grinding costs is achieved by using drum mills jointly with mills of other designs. The use of automation systems, slurry Technological cycle of iron ore crushing and grinding under production conditions is possible only in terms of mechanical load being rather labour-consuming and energy-intensive.

How iron ore is crushed? LinkedIn
In conclusion, iron ore is crushed through a three-stage crushing process involving primary, secondary, and tertiary crushers. The crushing process reduces the size of the ore particles, making itOption 2 has an additional grinding and magnetic separation stage compared to Option 1 and is considered to be simple for design and operation. The final milling stage is carried out using energy-efficient stirred mills. Steel grinding media usage significantly increases the operating cost.
