    The suppression of dust in coal-mines of Great Britain -thirty-second report to the committee on the control of atmospheric conditions and spontaneous combustion in mines-

    By J. Ivon Graham, T. D. Jones

    This paper presents methods in use in British coal-mines for the suppression of dust. While the effect of present-day treatment will not be apparent for several years, in pits in South Wales, concentr

    Characterization of feldspar texture and liberation by automated image analysis

    By W. Petruk, M. J. Matos

    An aplite ore from Guarda in northern Portugal, containing albite, microcline and quartz and muscovite gangue was studied to identify conditions for extracting the feldspar minerals. The large amounts

    The Constitution of Matte

    By Ruddle R. W.

    Solid mattes are generally held to be either (a) eutectiferous mixtures of the component sulphides Cu2S and FeS or (b) mixtures of complex sulphides. This chapter shows that liquid mattes consist esse
