    The sampling of air-borne mine dusts

    By D. G. Skinner, J. H. Griffiths, F. T. Williams, A. G. Withers

    "The absence of homogeneity, in dust-clouds underground indicates the use of a method in which the volume of air sampled is an appreciable proportion of the total volume under consideration. Of the av

    The Recovery of Sulphur From Smelter Gases

    By R. W. Ruddle

    The advent of new methods of roasting, “flash roasting and fluidisation”, which are now under development, combined with the use of oxygen-enriched air, may markedly increase the SO2 content of roaste

    Mossbauer effect study of reduction of ilmenite

    By R. Immele-Meziou, G. J. Long, D. G. C. Robertson, O. A. Pringle

    The reduction of naturally weathered ilmenite concentrate occurs in two steps: reduction of Fe3+ to Fe2+, followed by reduction of Fe2+ to Fe. Small amounts of a magnetic phase were also observed and
