Hematite: A primary ore of iron and a pigment mineral - GeologyThese are often in intimate association, and the ore is mined, crushed, and processed to recover both minerals. Historically, much of the hematite was not recovered and was sent to tailings piles. More efficient processing today allows more hematite to be recovered from the ore. The tailings can also be reprocessed to.hematite mineral crushing,Hematite Separation Process | Lolita Liao | Pulse | LinkedInNov 24, 2016 .
