The sulfuric acid method has a long process flow, heavy pollution, and low product quality. It is being gradually replaced by the chlorination method. The three wastes in the production process of the chlorination method are less, the environmental pollution is controlled, and the product quality is high. However, this process must use higher quality raw materials , such as high titanium slag, rutile, etc. Therefore, titanium concentrate must first be smelted in an electric furnace to obtain enriched TiO 2 The high-titanium slag can be connected to the chlorination process, the process is relatively long, and the economy becomes poor
[0006] It can be seen that the two main titanium-containing products after mining and processing of vanadium-titanium ore resources have certain deficiencies under the current technological conditions.

Abstract
The invention provides a treatment device of vanadium-titanium magnetite. The treatment device comprises a furnace body, temperature control equipment and air inlet equipment. The furnace body is composed of a sealing cover, a heat preservation and insulation layer, and a furnace wall arranged outside the heat preservation and insulation layer. A closed space formed by the sealing cover and the heat preservation and insulation layer serves as a furnace cavity. Temperature measuring equipment and heating equipment are arranged in the furnace cavity. The temperature control equipment controls the heating equipment according to the output temperature of the temperature measuring equipment. A crucible is arranged in the middle of the furnace cavity. A plurality of air holes are formed in the bottom of the crucible. The air inlet equipment conveys air to the air holes in the bottom of the crucible. Air exhaust equipment is arranged on the sealing cover. Air in the furnace cavity is exhausted through the air exhaust equipment. Compared with the prior art, by the adoption of the treatment device provided by the invention, solid-state reduction can be directly conducted on the vanadium-titanium magnetite, the reduction effect of the treatment device on the vanadium-titanium magnetite is good, the carbonation ratio is high, and the vanadium-titanium magnetite can be effectively utilized.
Description
technical field [0001] The invention relates to the technical field of metallurgy, in particular to a processing device and method for vanadium-titanium magnetite. Background technique [0002] Vanadium-titanium magnetite is a compound ore in which iron, vanadium, titanium and other valuable elements coexist. Among them, vanadium has many excellent physical and chemical properties, known as the metal "vitamin", and has a wide range of applications. Covering many fields such as aerospace, chemistry, batteries, pigments, glass, optics, and medicine. Titanium has stable chemical properties, high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, and high strength and low density physical and chemical properties. It can be alloyed with iron, aluminum, vanadium or molybdenum and other elements to produce high strength. Light alloys are widely used in aerospace, military, chemical, automobile, agricultural food, medicine, kitchen...
