Dispersion-flocculation studies on hematite-clay

1983-12-1  Int. J. Miner. Process., 11 : 285--302. Studies have been made on the separability of clay minerals such as kaolinite, illite and montmorillonite from hematite in dispersant-starch flocculant systems. The grossly different dispersibility of hematite from that of clay minerals aided separation by selec- tive dispersion and floceulation.

Selective Flocculation Separation of Fine Hematite

Beneficiation of ultrafine mineral particles (typically with an average size less than 20 µm) remains a critical problem for the mineral processing industry. Selective flocculation technique has been found to show great potential to tackle this problem, whose success mainly depends on the selective adsorption of a flocculant on the target mineral particles.
