Description
Technical field
The present invention relates to technical field of resource utilization, particularly relate to one kind titanomagnetite concentrate production DRI and
The method that nitrogen (carbon) changes titanium.
Background technology
Titanomagnetite is a kind of important iron ore resource, but the smelting of titanomagnetite concentrate is world-famous puzzle, and China passes through
Cross the research of technique of decades, it is achieved that technological break-through, currently form the titanomagnetite industry of " blast furnace ironmaking-pneumatic steelmaking "
Production procedure.But the technique is produced as dominating with iron and steel, and titanium is enriched in blast furnace slag, but because of TiO2Content low (less than 25%),
Thing is mutually complicated, and the technique that there is presently no maturation can be processed, and therefore greatly wastes the titanium resource of preciousness.Additionally, a large amount of
Blast furnace titaniferous slag store up, occupy substantial amounts of soil, while also result in water and soil pollution problem.Therefore it is badly in need of exploitation clean and effective
New technology improve titanomagnetite in titanium utilization rate.
Nitrogen (carbon) is changed titanium and has that fusing point is high, hardness is big, chemical stability is good and metal moistening is little, conductive and superconductivity
The features such as performance is good, nontoxic, be widely used in machining, cosmetic decoration, Aero-Space and war industry, electronics and battery and
The various fields such as medical apparatus and instruments.At present, nitrogen (carbon) is changed titanium and is mainly with high-purity Ti O2Or ilmenite is raw material, using carbon nitridation also
Prepared by former technique, carbon reduction-nitridation is needed with high-purity Ti O2Or ilmenite is raw material.Further, it is also possible to directly former in material surface
Titanium film is changed in position synthetic nitrogen (carbon), and it is physical vaporous deposition and chemical gaseous phase that the most frequently used nitrogen (carbon) changes titanium film synthetic method
Sedimentation.Both of which is that pure titanium distils, and reacts with nitrogen in high-energy vacuum environment.Also can at high temperature, by
The gaseous mixture of titanium tetrachloride-nitrogen obtains nitrogen (carbon) with the mixing solid/liquid/gas reactions of ammonia-hydrogen and changes titanium, or titanium-hydrogen-nitrogen mixed gas are heated
To high temperature by graphite, formation film on matrix material after cooling, is deposited on.Either physical vaporous deposition or chemical gaseous phase
Sedimentation is both needed to pure titanium as raw material, and synthesis condition is harsh, and therefore production cost is high.
In view of the difficulty that reclaims titanium products from titanomagnetite blast furnace process titanium slag is big, high cost, environmental pollution are big, grind
Personnel are studied carefully with titanomagnetite and coal as raw material, using hot carbon reducing process synthesis Fe-TiC (N) composite, but such material
Impurity content is high-leveled and difficult with application.
Content of the invention
The technical problem to be solved in the present invention is to provide one kind titanomagnetite concentrate production DRI and nitrogen (carbon)
The method for changing titanium.
The method specifically includes following steps：
(1) pelletizing：By titanomagnetite concentrate, carbonaceous reducing agent, additive and binding agent, mixing and water adding is made by a certain percentage
Ball or pressure ball；
(2) reduction roasting：After step (1) gained carbonaceous pelletizing is dried, reduce at 1200～1500 DEG C of sintering temperature
Roasting generates the roasted product for changing titanium comprising DRI and nitrogen (carbon)；The roasting of carbonaceous pelletizing is protected in reducing atmosphere or nitrogen
Carry out under shield, nitrogen atmosphere is conducive to nitrogen (carbon) to change titanium synthesis；Additive is added to have the effect that：A) promote iron mineral reduction
And nitrogen (carbon) changes the synthesis of titanium；D) metallic iron, nitrogen (carbon) is promoted to change growing up for titanium granule；C) gangue content is converted into readily soluble
In the material of acid, it is easy to the purification of subsequent nitridation carbon.
(3) ore grinding sorting：The roasted product of gained in step (2) is carried out ore grinding, then by low intensity magnetic separation or screening or
Person's low intensity magnetic separation-screening process integration obtains DRI and Ti-enriched slag；DRI is ferromagnetic substance, and granularity
Greatly, ductility is good, anti-wear performance is good, and other materials are weak magnetic or nonmagnetic, and general granularity is thinner, by low intensity magnetic separation or sieve
Divide or DRI can be separated with other materials by low intensity magnetic separation-screening process integration.Forming portion cyclotomy in roasted product
Screening after roasted ore simple crushing or ore grinding can be selected this portioned product by shape high-purity metallic iron coarse granule.Undersize is again
DRI and Ti-enriched slag are obtained through ore grinding, low intensity magnetic separation operation.
(4) acidleach purification：Gained Ti-enriched slag in step (3) is obtained High Purity Nitrogen (carbon) through the further remove impurity of acid solution and changes titanium
Product.The chemical property that nitrogen (carbon) changes titanium is extremely stable, insoluble in hydrochloric acid, sulphuric acid, phosphoric acid under room temperature, be slightly soluble in chloroazotic acid, nitric acid,
Fluohydric acid., therefore can be removed the impurity in Ti-enriched slag, obtain highly purified nitrogen (carbon) and change titanium products by acidleach.
Wherein, in step (1) titanium-containing magnet ore deposit concentrate used TFe grades>45%, TiO2Grade>5%.
In step (1) carbonaceous reducing agent be anthracite, bituminous coal, brown coal, graphite, coke, semicoke, petroleum coke, in biological Jiao
One or more combination；Additive be sodium carbonate, sodium sulfate, potassium carbonate, potassium sulfate, one or more group in sodium tetraborate
Close；In step (1), the mass ratio of titanium-containing magnet ore deposit concentrate, carbonaceous reducing agent, additive and binding agent is：100:(10～100):
(0～20):(0～10).
In step (2), roasted product is cooled down under air or nitrogen protection, or is burnt product through water quenching cooling.
In step (3), the grade of DRI is more than 90% more than the 90%, response rate.
In step (4) acidleach purification acid used for the one kind in hydrochloric acid, sulphuric acid, nitric acid, Fluohydric acid., phosphoric acid and perchloric acid or
Multiple combination.
The High Purity Nitrogen (carbon) obtained in step (4) is changed the purity of titanium valve body and is more than 99%, and titanium recovery rate is more than 90%.
The above-mentioned technical proposal of the present invention has the beneficial effect that：
In such scheme, directly by titanomagnetite production direct-reduction iron product and the high-purity titanium products of nitridation, with raw material
Wide material sources, flow process are short, value of the product is high and the characteristics of environmental friendliness, and green high-efficient make use of ferrum in titanomagnetite, titanium, vanadium
Resource.DRI and the response rate of the response rate more than 90%, Iron grade more than 90% are more than 99% more than 90%, purity
Nitrogen (carbon) changes titanium products.
