The Bayer process, storage and transport of smelter grade alumina (SGA) together contribute to the unique particle size distribution of the SGA as received in a gas treatment facility or in a reduction cell hopper. Pore size distribution analyses of alumina fractions indicate that the +125μm, +90μm -125μm, +63μm -90μm and +45μm -63μm particles possess similar total pore volumes. The total pore volume of -45μm particle size fraction was found to be approximately 15% lower than the remaining bulk. Having earlier studied the evolution of pore size distribution in the bulk SGA during fluoride scrubbing, this work examines the interplay between particle and pore size distributions, with focus on the impact of fines on scrubbing efficiency in a smelter GTC.
