Magnetic Separation Hematite Taconite

The Geology and the recent development of taconite and DSO

• The magnetite associated with chert/jasper is fine grained, with minor amounts of hematite, carbonates and silicates. This ore is amenable to produce magnetite concentrates by fine grinding the ore and by magnetic separation methods.
