Embodiment Construction

[0010] The extraction method of iron-vanadium-titanium ore, firstly, roasting is carried out to separate iron and titanium, titanium and vanadium are leached, iron is reduced and roasted, and the vanadium in the raw ore is extracted by adding industrial chemical additives, and processed into vanadium dioxide;

[0011] Then, by adding industrial chemical additives, the titanium element is extracted and processed into titanium dioxide;

[0012] Finally, the raw materials are processed again, and chemical additives and reducing agents are added to increase the content of the reduced iron powder to more than 95% of (TFe). Described industrial chemical auxiliary agent is: Smelting Coke 6% weight portion, CaMg (CO 3 ) 2 3% by weight, CaCO 3 2% by weight, CuO 2% by weight, Fe 3% by weight, HCl 3% by weight, MnO 2 1.5% by weight, FeCl 3 parts by weight, NH 3 ·H 2 O weight part, 2% NaOH weight part, 3% all the other are conventional fillers.

[0013] The remaining raw materia...

Abstract

The extraction method of iron-vanadium-titanium ore, firstly, roasting is carried out to separate iron and titanium, titanium and vanadium are leached, iron is reduced and roasted, and the vanadium in the raw ore is extracted by adding industrial chemical additives, and processed into vanadium dioxide; , by adding industrial chemical additives, then extracting the titanium element, and processing it into titanium dioxide; finally, the raw materials are processed again, and chemical additives and reducing agents are added to increase the content of reduced iron powder to more than 95% (TFe). The beneficial effect of the present invention is that by adding industrial chemical additives and reducing agents, and then heating and processing, the grade of iron can be increased to more than 95% (TFe), which greatly improves economic benefits and reduces production energy consumption Cost, to achieve resource reuse, effective utilization, environmental protection and other technological leaps, greatly beneficial to human health and environmental protection.

Description

technical field [0001] The invention relates to a method for extracting iron-vanadium-titanium ore, which belongs to the metal extraction technology for smelting refractory ores. Background technique [0002] my country's iron-vanadium-titanium ore is widely distributed, rich in resources and large in reserves. However, most of them belong to lean ore, the processing cost of traditional technology is extremely high, and it is usually impossible to process and extract, resulting in that this kind of resource cannot be well extracted and recycled. All kinds of crazy elements in it are extracted and processed into high-grade ore. It causes a great waste of resources, which is not conducive to environmental protection, nor is it conducive to the recycling of resources. Contents of the invention [0003] In view of the above problems, the iron-vanadium-titanium resources are widely distributed and the reserves are large and cannot be well utilized. After years of research and...
