    Following fine crushing, the ore is directed to dry cobbing, which is a dry magnetic separation process used to reject the portion of the ore that does not contain sufficient magnetic iron. The ore not rejected during dry cobbing is sent to a series of wet grinding and concentrating processes to separate, concentrate, and recover the iron from the incoming ore.
