    An instrumented leach column for the study of sulphide oxidation in waste heaps
    (Australian Atomic Energy Commission, 1985-05) Lowson, RT; Sarbutt, JV
    The construction commissioning and first year of operation of a large scale instrumented leach column are described. The column material was sulphidic mine overburden. Monitored parameters included matrix potential temperature redox potential dissolved oxygen pore space gas water addition and drainage together with pH, Cd, Cu, Fe, Ni, Zn, Cl, F, SO42 and PO43 in the effluent.

    The rum Jungle tailings dam - chemical profile of the subsoil
    (Australian Nuclear Science and Technology Organisation, 1987-09) Lowson, RT; Evans, JV; Sarbutt, JV; Sinclair, G; Folk, E
    In a survey of soils below the Rum Jungle uranium mine tailings dam parameters measured were pH moisture content particle distribution total Cu water-extractable Cu, Ca and SO4 and acid-extractable Ra. The cation profile had a marked discontinuity at the soil/tailings interface. This was attributed to a complex hydrogeology and to the presence of a reduction zone in the soil immediately below the tailings. The tailings acted as an aquaclude to a water table which fluctuated with the monsoonal season. The reduction zone acted as a cation trap preventing cation transport. The radium concentration dropped to levels acceptable to public health within a few centimetres of the soil/tailings interface.
