Переработка экологически опасных ванадийсодержащих промышленных отходов

Abstract

Demand for vanadium and its compounds increases. This leads to an increase in interest in the processing of spent va- nadic catalysts (SVC) of sulfuric acid production and solid combustion products of fuel oil in thermal power plants. In or- der to intensify the leaching stage and increase the degree of vanadium compounds extraction the processes of the reduc- tion leaching of vanadium components from the SVC in acid solutions containing reducing agents have been studied. Op- timal concentrations of reductions in the leaching solutions have been determined.
