Recovery of vanadium from black shale LI Cun-xiong(李存兄), WEI Chang(魏 昶), DENG Zhi-gan(邓志敢), LI Min-ting(李旻廷), LI Xing-bin(李兴彬), FAN Gang(樊 刚) College of Metallurgical and Energy Engineering... ____________________________________________________________________________________________ Abstract: The recovery of vanadium from a black shale from Guizhou Province of China was performed using a three-step process, which consists of a leaching step in the H2SO4-HF-NaClO system......
: A hydrometallurgical process for the selective removal of silicon from titanium–vanadium slag by alkaline leaching was investigated. X-ray diffraction, scanning electron microscopy and electron dispersive..., hindering filtration and separation in the subsequent water leaching process. Therefore, removal of the silicon from the titanium–vanadium slag is necessary prior to the NaOH molten salt decomposition......
In Situ Growth of Vanadium Oxide on Reduced Graphene Oxide for the Low-Temperature NO-SCR by NH3李美颜1,QI Yanyuan2,金伟1,JIAO Binqing1,ZHAO Jie11. State Key Laboratory of Silicate Materials...">The vanadium oxide/reduced graphene oxide(V2 O5/rGO) composite catalyst which determined the selective catalytic reduction activity(SCR) of NO with NH3 was prepared by a simple solvothermal method......
used as precipitating agent to remove vanadium. The amount of iron salt added, pH value, temperature and other major factors on the impact of vanadium removal were investigated, the optimum conditions..., vanadium is adsorbed on the surface of the iron hydroxide by inner layer complexation. Key words: sodium chromate; vanadium removal; non-calcium roasting; ferric hydroxide; adsorption 铬盐是重要的无机化工原料,产品主要应用于......
