)Abstract:Extracting vanadium and removing phosphorus simultaneously by adding CaO containing materials to V-bearing hot metal were investigated under the condition of simulating the process of vanadium..., respectively. The results of the formal experiments suggest that making basic slag can extract vanadium and remove phosphorus simultaneously. The vanadium extraction rate (ηV) and phosphorus removal rate......
energy, wind energy and some other renewable power resources. Compared with others, all vanadium redox flow battery(VRB) proposed by SUM et al[1-2] has such unique advantages as low cost, long cycle life... Characteristics of graphite felt electrode electrochemically oxidized for vanadium redox battery application LI Xiao-gang(李晓刚)1, HUANG Ke-long(黄可龙)1, LIU Su-qin(刘素琴)1, TAN Ning(谭 宁)1, CHEN Li......
be economically utilized. In addition, the contents of harmful elements, e.g., S, P, and Zn are lower than permitted load of BF. For vanadium titano-magnetite in China, GAN et al [9] maintained that the metallurgical properties of sinters got worse after adding vanadium titano-magnetite in mixed sintering materials in Panzhihua Iron and Steel Corporation, China, and lots of iron and slag could not get......
Removal of vanadium from ammonium molybdate solution by ion exchange LI Qing-gang(李青刚)1, 2, ZHANG Qi-xiu(张启修)2, ZENG Li(曾 理)2, XIAO Lian-sheng(肖连生)1, 2, YANG Ya-nan(杨亚男)2 1. State Key Laboratory...; Abstract: The separation techniques of vanadium and molybdenum were summarized, and a new method of removal V(Ⅴ) from Mo(Ⅵ) by adsorption with chelate resin was presented. Nine......
-leaching on account of its catalysis oxidation for the dissolution of valuable metals [8, 9]. Studies have been conducted in the applications of A. ferrooxidans in vanadium ore. HUANG et al [10] and LIAO et al [11] reported the biological process of vanadium-bearing stone coal using A. ferrooxidans. According to the literature, A. ferrooxidans could lower the toxicity of waste catalyst......
phase through hydro- leaching and is precipitated from the solution upon adding ammonia and controlling the pH via sulphuric acid. After removal of the ammonia, the vanadate can be converted... to form more Ca-V-rich phases. It is worth mentioning that the high Al content shown in Fig. 5 may be from the alumina tube used in the melting oxidation experiment. Fig. 4 Vanadium 2p photoemission......
and hot metal have been reported in many previous studies [13-26]. JUNG et al [16] and SHIN et al [17] indicated that the vanadium distribution ratio between slag and molten iron increased with the increase of slag basicity but decreased with the rise of temperature. However, WANG et al [23] showed that the distribution ratio of vanadium between titanium slag and molten......
Abstract: In order to reduce the pollution of Cl2 and HCl released during extracting vanadium from stone coal by sodium chloride roasting, a modified salt-roasting process was proposed by adding...-to-solid ratio was 2 mL/g, the adding sulfuric acid was 3.5 mL, and the leaching temperature was room temperature. The contents of vanadium in the stone coal samples and the leached residue were analyzed......
. However, it was found in our laboratory that AlN could be effectively oxidized by roasting SAD with adding cryolite at about 700 °C, which realizes the removal of it. Besides, the activity of the dross... J. Cent. South Univ.
