and the sedimentation experiments. The results indicated that the yttria and alumina powder mixtures were well dispersed by the dispersing agents. The rheological curves showed shear thinning behavior......
characteristics of sedimentation volume and accumulation density are obviously better than those of carbonate precipitation products. The carbonization method can be used not only to obtain ultra-fine rare earth......

concentrates in the ferric chloride media, selective purification and chemical sedimentation, PbS concentrate can be converted into PbSO4. The conversion recovery is 97.39%, the purity of PbSO4 powder..., in this work, a new approach of preparing PbSO4 from galena concentrates in ferric chloride media coupled with selective purification and chemical sedimentation was proposed. Compared with traditional process......

) or citric acid lanthanum chelate (NH4-La-CA) was investigated. The dispersion property was characterized with sedimentation value. It is easier to obtain well dispersed slurry with NH4La-CA than NH4-CA... was treated with ultrasonic dispersing for 5 min again, and a sedimentation electronic balance was used to determine the sedimentation volume at 30 ℃. Two kinds of the colloidal with citric acid lanthanum......
by sedimentation test, zeta potential measurement and SEM observation. SEM images reveal that kaolinite particles show the self-aggregation of edge-face in acidic media, the aggregation of edge-face and edge-edge... with cationic surfactants[15-18]. In this work, the hydrophobic aggregation of kaolinite was investigated through zeta potential measurement, SEM observation and sedimentation test. 2 Experimental 2.1......
