Extraction of vanadium-conataining products from the sludge of thermal of thermal power stations

Abstract

In the Republic of Belarus a potential source of vanadium-containing secondary raw materials is vanadium-containing sludge generated by the combustion of fuel oil in the boiler units of power plants. Vanadium concentration there is ten times greater than its content in the traditional ore raw materials. The total number of vanadium-containing sludge on the territory of the Republic of Belarus for the beginning of 2012 wasdetermined. Methods of vanadium-containing compounds extraction from vanadium-containing sludge ThPS were developed with the use of hydrometallurgical method. The methods influence of the vanadium-containing compounds extraction from sludge of ThPS on their composition and amount of extraction was studied
