Research on Properties and Mechanism of Dispersant for High  Phosphorus Hematite in Western Hubei

Abstract

Abstract: Taking the high phosphorus hematite in western Hubei as the object，tests on the dispersion effect of sludge with the type and dosage of dispersant，slurry pH value，stirring time after adding dispersant are made.The action situation of dispersant in coagulation among fine mineral particles and slime coating is studied，and the optimal dispersion conditions are given.Then，the mechanism of dispersion action and the reasons for different dispersion effect of dispersant in the tests are theoretically analyzed.

Key words: Oolitic hematite, Fine particles, Dispersant, Total energy
