on the vanadium extraction from titanomagnetite is shown in Figure 1 The vanadium extraction appears to be insensitive to variations in NaCl concentration in the studied range, as shown by the almost constant vanadium extraction of 64% and 63% at NaCl concentrations of 5% and 15%, respectively Figure 1 1 Introduction The vanadium–bearing titanomagnetite (VBT) is a strategic and complex iron ore, which containing valuable metals of vanadium, titanium, and iron used as constituents of several alloys, whitepigments, and steel , , In China, the gross reserve of titanium in VBT ore is estimated to be about 118 million tons, accounting for 93% of China’s total domestic reserve of titanium Efficient separation of vanadium, titanium, and iron Deposits of titaniferous magnetite, uraniferous sandstone, bauxite, phosphate rock, crude oils, oil shale and tar sands host vanadium Apart from titanomagnetite and ilmenite ore deposits containing vanadium, slags from the ferrous industry are a major source of supplyProcessing of vanadium: a review ScienceDirect
NEW PROCESS OF EXTRACTING VANADIUM FROM
The new process of vanadium extraction from molten vanadium slag by direct oxidation and sodium activating method is reasonable and feasible The experimental results show that in the new process, vanadium in the roasted slag exists mainly in the form of watersoluble sodium vanadate and the vanadium water leaching efficiency can reach to 80%,Extraction of titanium, vanadium and iron from DeepDyve Read Extraction of titanium, vanadium and iron from titanomagnetite deposits at pipestone lake, Manitoba, Canada, Minerals Engineering on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips Get Priceiron vanadium titanium deposits lafermeduvar1 The method of extracting vanadium from titanomagnievyj toxins, including grinding of slag, oxidation firing his translation of vanadium in soluble form, cooling the burnt slag leaching it with the extraction of vanadium in solution, characterized in that the firing of lead slag in the temperature range 1501150°C without additives or with the introduction of CaCO 3 within 1545 min, and Method of recovery of vanadium from titanium
