There's a new plan to unlock a magnetite mining hub in WA
The magnetite operations that did manage to get up and running generally performed poorly. (There are two main types of iron ores – hematite and magnetite. Hematite is a higher grade in the ground, while magnetite deposits are large and quite low grade – but produce super high-grade products.)
Processing – Karara Mining
The additional processing cost for the production of magnetite concentrate can be offset by the premium price which it attracts from steel mills because of the high iron content compared to benchmark DSO hematite products. Magnetite ore known as Run-of-Mine (ROM) material is direct dumped by haul trucks from the mine into the primary crusher.
