Processing

The Yarrabubba ore requires simple crushing / grinding and magnetic separation to produce a high grade iron-vanadium magnetite concentrate with grades >63% Fe and >1.6% V2O5. The tails material is further beneficiated using gravity methods into a >46% TiO2 titanium concentrate. A schematic diagram of the flow sheet (shown below) highlights that it is the same crushing and benificiation infrastructure that will be used for the Gabanintha ore.

The Market for Yarrabubba's Iron-Vanadium Magnetite Concentrate 

Several Chinese steel mills are designed to produce a vanadium slag from vanadium bearing magnetite ore. Historically, the feed material of these mills comes from domestic mines with lower iron and vanadium grades when compared to Yarrabubba.  The schematic below describes the smelting process and the point at which the vanadium slag is “tapped” and then concentrated to produce vanadium products.
