Extract

A program of ore reserve and grade determination on a major bauxite deposit has recently been completed. More than 2,000 samples were chemically analyzed for available Al2O3, reactive SiO2, loss on ignition; and by energy dispersive XRF for a total Al2O3, SiO2, TiO2, and Fe2O3. As compared to standard wet chemical analytical methods, the XRF analyses proved to be cost and time effective, and the observed analytical precision was superior.
