Abstract
In China, the comprehensive utilization of vanadium and titanium resource is an important scientific and technological issue. Meanwhile, energy conservation and environmental protection is much more serious than ever before. In the traditional process for vanadium extraction, the roasting process is the key step for oxidize V (III) and V(IV) to V (V) of the vanadium slag by presence of NaCl or CaO, but it results in serious environmental pollution and energy consumption. For elimination the roasting process in vanadium extraction and utilize the spent acid in titanium dioxide production, this paper reports a novel technology for vanadium extraction: leaching the vanadium slag with the spent acid for titanium from titanium dioxide production.
