Abstract

The formulation and stabilization of highly concentrated solid-water slurry for transportation are gaining high interest. The influence of saponin extracted from A. auriculiformis on the stabilization of a high-grade iron ore sample in the slurry was studied. The collected iron ore powder and dried iron ore slurry samples were compared with the help of UV-vis, XRF, XRD, SEM, and EDS analysis. Moreover, the DSC spectral graph for both heat flow and mass loss with respect to time is plotted. The results confirmed that the surfactant molecules (aqueous A. auriculiformis) coated well on the iron surface which form an effective barrier between the iron ore particles. Further, the solubility of iron ore powder increased after adding an aqueous extract of Acacia auriculiformis as evident from the UV-vis spectral study.

探讨生物表面活性剂在高浓度铁矿矿浆稳定中的作用

输送用高浓度固水浆料的配方及稳定性已引起人们的高度关注。研究了木耳中提取的皂苷对高品位铁矿料浆稳定性的影响。采用紫外可见光谱(UV-vis)、XRF、XRD、SEM和能谱分析(EDS)对采集的铁矿粉和干燥后的铁矿浆样品进行比较。此外，还绘制了热流和质量损失随时间的DSC谱图。结果证实，表面活性剂分子(水合耳木耳)在铁表面包覆良好，在铁矿颗粒之间形成了有效的屏障。此外，从紫外可见光谱研究中可以看出，加入金合欢水提取物后，铁矿石粉的溶解度增加。
