    Minimum recovery zone height in flotation columns from particle-bubble collision analysis

    By J. A. Finch, Zhenghe Xu, Z. A. Zhou

    A particle-bubble collision model was used to investigate the minimum recovery zone height, H(r,min) required for flotation columns. The criterion used to define H(r,min) is that height which gives un

    Development of Schytill and Geldart diagrams for determining the fluidization conditions for chlorination of anatase-charcoal mixtures

    By R Adamian, F. T. Da Silva, D. H. Gameiro

    Schytill and Geldart diagrams were developed for the TiO2-C-Cl2 system at 1 073 and 1 273 K, so as to define the hypothetical relations between particle sizes and chlorine velocity for simultaneous fl

    Behaviour of magnesia-bearing fluxes during iron ore sintering

    By B. M. England, L. C. Mackey

    Magnesia minerals are included in most iron ore sinter mixes to provide the MgO requirements of blast furnace slag. The properties of these minerals have an influence on the eventual sintering propert

    Selective chlorination of iron from synthetic pseudobrookite

    By F. C. Gennari, D. M. Pasquevich

    With the gradual exhaustion of natural rutile, there has been extensive research into its synthesising from lower-grade titanium minerals. The removal of Fe from pseudobrookite (Fe2TiO5) by chlorinat
