The invention relates to a comprehensive recovery process for vanadium titano-magnetite. The comprehensive recovery process comprises the following steps that vanadium titano-magnetite fine powder is uniformly mixed, pelletized and dried, and reduced through a shaft furnace to obtain high-carbon deoxidized pellets, the high-carbon deoxidized pellets are added into a titanium slag furnace to be smelted, and titanium slag and vanadium-containing molten iron is obtained; and then the vanadium-containing molten iron is added into a vanadium slag furnace for oxygen blowing and tempering, and vanadium slag and molten steel are obtained. Compared with the existing vanadium titano-magnetite recovery process in the world, the process not only has the remarkable advantage of recycling three valuable components of vanadium, titanium and iron in the vanadium titano-magnetite, but also has the remarkable advantages of high yield, low production cost, good product quality, remarkable economic benefit and the like; and in a
