These separators utilize strong magnetic fields to separate iron minerals from lower-grade non-magnetic ores. The efficiency of this separation process is largely determined by the Fe content, or iron content, of the ore. High-grade iron ores, with a higher Fe content, are more valuable and therefore more profitable to process. Related News
