silica-rich magnetite ore is presented in this paper200 energy saving and fine granularity. According to the specific production requirements fine-grained the utilization rate of ore can reach 90% high crushing ratio000 tons of crude ore were mined and separated in 1916. The dry process of separation is used.Edison and Ore Refining Engineering and Technology. This mill pulverized the large chunks of ore that came directly from the mine Edison planned to process 1200 tons of iron ore every twenty hours The plant had three magnetic separators that could produce a total of 530 tons of refined ore There was other equipment to rerefine what was left over to extract even more ore …Beneficiation circuits in magnetite operations involve upgrading of ore with iron content of 10-35% Fe to a concentrate with grades between 60-70% Fe and involves stages of mineral liberation (crushing
