Processing and Potential Utilisation of Variable Grade Western Australian Diatomite Deposits
The Engineering Chemistry Division of the Government Chemical Laboratories of WA initiated an ongoing investigation into the possible utilisation of diatomites of this State. The work has shown that local diatomites can be beneficiated by hydro or pneumatic cyc- lone separator circuitry and that the better quality head materials can be upgraded by straight and flux calcination and associated processing to the equivalent of premium grade imported products. Western Australian diatomites vary con- siderably in quality, and the degree to which they can be upgraded and the yield of useful product are influenced by the proportion of impurities and the size, type, and degree of fragmentation of contained diatoms. Conseq- uently careful assessment of ore deposits will be necessary in order to relate ore reserves to planned production. The viability of commercial production from Western Australian resources would hinge on the establishment of markets - largely ex- port - capable of supporting a production level of the order of 30,000 tonnes per annum.
