Hematite Processing by Flotation

Hematite Flotation Circuit Each flotation circuit consists of a four cell open flow roughing section followed by a two cell scavenger. The scavenger concentrate is returned by gravity to the third rougher cell and the rougher concentrate from the first rougher cell is sufficiently high grade ( + 58% Fe) to combine with the cleaner concentrate which flows by gravity to the recleaners.
