Sep 06, 2013 With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore. That means it has to be concentrated before it can be used to produce steel. However, the ore’s magnetic properties help separate magnetite from rock during concentration.The ore dressing process of treating poor hematite includes staged ore milling, size separating, gravitational dressing, strong magnetic dressing and inverse floating. By means of staged ore milling, early separation between iron containing mineral and gangue, returning the intergrowth to next ore milling for further separation, separating milled material based on size, gravitational dressing ...
