DETERMINATION OF THE DISPERSING FORCE OF DISPERSANTS IN FINE-GRDUND IRON ORE SLURRY AND THEIR ACTIVE MECHNISMS

In this paper, for the hematite with 70. 26% of - 20μm particle of the Si jiaying Iron Minein Eestern Hebei Province, the dispersing stability of dispersants such as natrium carbonate, sodium silicate,acidated sodium silicate, salted acidated sodium silicate and sex-unsymnatrium phosphate are analysed, themeasured electric potentional of different densities of above-mentioned dispersants are reported, and theiractive mechanisms are discussed.
