Together with the University of Innsbruck an extensive Feasibility Study was done regarding the possibility to use SpectraFlow to measure Bauxite ore. As SpectraFlow can identify the mineralogical phases it is possible to distinguish between the different Bauxite minerals (Gibbsite, Kaolinite and other iron containing minerals). With this information the stockpile can be optimized according the Silica allowance in the Bayer process.
