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

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

Vanadium-containing wastes recycling for enterprises using fuel oil: high expectations

Demand for vanadium and its compounds grows: vanadium compounds are extensively used in various industries. Vanadium compounds extraction from industrial wastes is more cost-effective than from natural raw materials. In Belarus, sludge from thermal power plants and wastes of sulfuric acid manufacturers are the sources of secondary vanadium-containing raw materials. Vanadium-containing wastes generation and accumulation in the territory of the Republic of Belarus for recent years are analyzed. The article demonstrates that the development and implementation of recycling procedures for these wastes will resolve environmental problems and save valuable substances not common in nature but applicable in industrial production in the Republic of Belarus

Methods for processing ash residues of TPS vanadium containing slurry

Application of vanadium industrial waste complex processing provides the decision of two main tasks: expanding the raw material base for extremely scarce metal and reduction of an environmental impact on nature. Combined and hydrometallurgical methods of vanadium extraction from the ash residues of TPS vanadium sludge have been developed. These methods allow to extract up to 95% of vanadium that contains in waste, and to obtain a vanadium product suitable for using in different areas of industry
