Acidic full-vanadium-titanium pellets and preparation method thereof

The invention discloses a preparation method for acidic full-vanadium-titanium pellets using high-titanium vanadium-titanium magnetite. The method comprises the following steps of: proportioning, mixing, drying, wet-milling, pelletizing, drying, preheating, baking, cooling, screening and like. The raw materials for the pellets provided by the invention mainly comprise full-vanadium-titanium magnetite concentrate, the ratio of which can be up to 100%, a small amount of a binder is mixed for pelletizing and baking is carried out to prepare the finished product pellets. Using the method provided by the invention to prepare the acidic full-vanadium-titanium pellets has wide range of raw materials, especially solves the difficulty in the pellet manufacture from vanadium-titanium magnetite concentrate and lowers the manufacture cost of the pellets by using single full-vanadium-titanium magnetite concentrate to process pellets, and the technical and economic indexes such as utilization coefficient and coke ratio of the blast furnace using the acidic full-vanadium-titanium pellets for smelting are improved.
