. With increasing addition of calcium ferrite, A/S and N/S in the red mud are reduced. Under the conditions of higher digestion temperature and longer time, A/S in the red mud is reduced with lower bauxite addition. Under the condition of 250 ℃, 60 min and adding calcium ferrite, large scale experiments have been done, which results in that A/S in the red mud is 0.69, N/S is 0.21. The main Si-mineral of red......

Red Long Lasting Phosphorescence of Mn2+ Doped Zinc Phosphate Glasses廉志红,苏锵摘 要:<正>Mn2+ doped ZnO-P2O5 glasses emit red fluorescence,which shows that Mn2+ ion doped in zinc phosphate glass is octahedrally coordinated.Moreover,glass samples exhibit bright red long lasting phosphorescence (LLP) when the mole percent of ZnO are more than 60%.After......
process was accomplished. The results show that in three thickening test stages of mud bed height 25, 45 and 70 cm with the same rake shear ratio 15 r/min, the amount of aggregates diameter over 100 μm... diameter decreases as shear time mud bed height increases, and the aggregate densification accelerates with mud bed height rises. As the function of effective aggregate diameter, the effective hinder......
