    Polyacrylate flocculation of haematite in synthetic Bayer liquors has been studied to determine the effect of increasing caustic strength and carbonate concentration. The drop in flocculation efficiency observed with increasing caustic concentration (0.09 to 6.23 M) was shown not to be due to changes in the flocculant adsorption density or the

    Enhancement of Hematite Flocculation in the Hematite

    In the iron ore industry, the flocculation of hematite with starch in the presence of a dispersant for gangue minerals is important for the production of high-grade concentrates. The sequence of reagent addition in this process has been considered negligible as starch was reported to have no significant effect on the adsorption of other reagents in the literature.

    In the first flocculation stage, the hematite particles are preferentially adsorbed onto the schizophyllan aggregates in solution. The second stage consists of the association of these reactive entities with each other and also with naked chains to form fractal flocs by a bridging mechanism, where the hematite particles play the role of ligands.
