Physical Properties and Hydration of Cementitious Materials Prepared from Vanadium Slag and Phosphate Slag张鹏羽1,2,OU Leming1,2,刘琨1,3,LI Wentao11. School of Minerals Processing & Bioengineering... from the vanadium slag and phosphate slag, were investigated. These slags were investigated can be reused as original resources to prepare cement clinker based on the fact that they mainly comprise......
-Fe powder can promote titania enrichment and make perovskite phase grow up easily. While air is blown into the molten slag, the reduced components in slag are oxidized and the released heat raises... size and complex interfacial combination, the application of these processes may result in poor recovery and high cost. Fortunately, when the molten slag was carefully treated after it effused from......
Direct electrochemical reduction of solid vanadium oxide to metal vanadium at low temperature in molten CaCl2-NaClZhuo-fei Cai, Zhi-mei Zhang, Zhan-cheng Guo, and Hui-qing Tang State Key Laboratory... as the cathode and the anode, respectively; a molten CaCl2-NaCl salt was used as the electrolyte. Then, V2O5 was directly reduced to metal vanadium by the Fray-Farthing-Chen (FFC) method at 873 K to realize......
was introduced to the difficult grinding of air quenching steel slag by a series of experiments. The results show that the fly ash added into the molten steel slag before air quenching can more... alkalinity, it is difficult to form glassy phases in steel slag[5-6]. Air quenching of steel slag is a process to use high-pressure air to cool molten steel slag from high-temperature rapidly to form......
–acid leaching of high-chromium vanadium slag(HCVS)was conducted to elucidate the roasting and leaching behaviors of vanadium and chromium.The effects of the purity of Ca O,molar ratio between Ca O...Roasting and leaching behaviors of vanadium and chromium in calcification roasting–acid leaching of high-chromium vanadium slagJing Wen1,Tao Jiang1,2,Mi Zhou1,2,Hui-yang Gao1,Jia-yi Liu1,Xiang-xin......
Oxidation process of low-grade vanadium slag in presence of Na2CO3 LI Xin-sheng, XIE Bing, WANG Guang-en, LI Xiao-jun College of Materials Science and Engineering, Chongqing University, Chongqing 400044, China Received 20 October 2010; accepted 20 January 2011 Abstract: The oxidation process of low-grade vanadium slag in the presence of Na2CO3 was investigated by XRD, SEM/EDS and TG-DSC......
University, Shenyang 110004, China) Abstract: Oxidization mechanism in CaO-FeOx-SiO2 slag with high iron content was investigated by blowing oxygen into molten slag so as to oxidize Fe..., hematite, silica and calcium oxide in alumina crucible, heating in argon to 1380℃ and holding at this temperature for 1h. The crucible was taken out of furnace and the molten slag was immediately poured......
