This work gives the results of researches of processing of wastes, formed as a result of refinement from impurities of technical titanium tetrachloride. Hydrocarbonic reducer and cascade-rectifying refinement are offered for refinement of technical titanium tetrachloride instead of the method, based on application of aluminium powder. Usage of these refinement methods leads to formation of anthropogenic wastes: carbonaceous cake, vanadium distillate and limed cake. The researches have shown that processing of these wastes is reasonable for the purpose of vanadium pentoxide extraction. Processing of carbonaceous cake includes leaching in muriatic solution, filtration and sedimentation from required product solution with its subsequent calcination. Provision of production of calcium vanadate or vanadium pentoxide is possible during the reprocessing of carbonaceous cakes. Production of calcium vanadate is connected with usage of rather cheep and accessible reagents, but its consumer worth is not high. Production of vanadium pentoxide requires more expensive reagent (soda), but it is more valuable product. The reprocessing circuit design of vanadium distillate includes dissolution in water, solute distilling in cyclic mode, filtration and calcination of sediment. Processing of limed cake includes washing out from chlorine-ion, oxidizing roasting, leaching of obtained calcine, sedimentation from solution and calcination of vanadium hydroxide. In laboratory conditions, degree of vanadium pentoxide extraction at processing of carbonaceous cake, vanadium distillate and limed cake was 92–96%, 92–94% and 93–95%, respectively. In addition, processing of anthropogenic wastes will make possible to lower the anthropogenic impact on environment.
