nvestigation of Methods for Processing Sludge Liming Sewage Hydrometallurgical Production of Vanadium Pentoxide


The sediment of neutralization of drain waters, or the sediment of liming, is obtained by processing with lime milk solutions of hydrometallurgical production of vanadium pentoxide containing sulfuric acid, followed by filtration. A scheme of processing to obtain vanadium concentrate is proposed.

Keywords: sludge liming sewage, vanadium pentoxide, leaching, filtration, washing, deposition, concentrate
