Abstract [en]

Direct measurement of the porosity variation in filter cakes by image analysis has been tested on chalcopyrite and magnetite slurries. It was found to give more accurate results than previous indirect methods, especially at the surface of the cake. Microscopy and image analysis visualize the effect of particle size, particle segregation and air bubbles on cake porosity. In a filter cake formed under constant pressure, the maximum porosity is shown to occur in regions inside the cake, rather than on the surface.
