Selective Flocculation of Banded Hematite Quartzite

2016-6-11 · The banded hematite quartzite iron ore is a low grade iron ore and contains only 39% Fe, with 42.5% SiO2, and 1.0% Al2O3. The mineralogical characterization studies indi-cate the presence of hematite and quartz as the major miner-als. The initial flocculation experiments with synthetic mix-ture of hematite and quartz indicates a hematite concentrate of 64.5% Fe with 92.0% recoveryis achievable from a feed containing 34% Fe. Selective flocculation results with custicised starch as the flocculant to recover iron values from the sample indicates that it is possible to separate the iron values from other impurities at pH 9.0. The change of absorption peaks of starch through FTIR provides evidence the adsorption of starch on hematite particle present in BHQ. These particles agglomerate as viewed under SEM. The results of selective flocculation studies
