Our Analytical Services Division laboratory conducts mineralogical and chemical analyses on bauxite, alumina, Bayer liquor and water samples. Some analyses we do include:
Bauxite: Total Available Alumina (TAA), Available Alumina (AA), Reactive silica, Moisture, Loss on Ignition, X-ray Diffraction (XRD) (with XDB), X-ray Fluorescence (XRF), and elemental analyses via Inductively Coupled Plasma (ICP)
Alumina: X-ray Fluorescence (XRF)
Bayer Liquor: Alumina, Caustic and Total soda and elemental analyses via Inductively Coupled Plasma (ICP)
Bauxite residue (red mud): X-ray Fluorescence (XRF) and elemental analyses via Inductively Coupled Plasma (ICP)
Water: pH, Total Dissolved Solids (TDS), electrical conductivity, Salinity, Sodium, and elemental analyses via Inductively Coupled Plasma (ICP)
Statutory Analyses
We analyze a sample from each shipment of bauxite exported for quality assurance.
Commercial
The JBI’s laboratory assesses bauxite for processability. This informs how a bauxite
feedstock will behave during the different stages of the Bayer process under varying
conditions. We can assess:
Pre-desilication
Digestion
Settling and
Mud-washing
