D. taking out the block-shaped materials, and crushing and grinding the block-shaped materials;
E. and carrying out magnetic separation on the obtained powder, wherein the selected iron-containing powder is TiC-enriched refined slag.
The principle of the invention is as follows: at 1400-1600 ℃, only TiO in each component in the titanium-containing blast furnace slag2The reduction carbonization reaction can be carried out, and TiC crystal grains are easy to enrich and grow around iron grains, so that through specific material proportion and high-temperature treatment, the iron-containing coke is used for reduction carbonization of the titanium-containing blast furnace slag, so that most Ti elements in the slagThe element exists in a TiC form selectively, TiC crystal grains are enriched and grown around iron grains, and the size of the obtained Fe-TiC combination is far larger than the requirement of mechanical beneficiation separation, so that the separation of the Fe-TiC combination in the carbide slag can be realized through magnetic separation.
The iron-containing coke used in the step A can adopt intermediate products in other processes, and can also be prepared in the following mode, and the method specifically comprises the following steps:
a. uniformly mixing and grinding the coking coal and the iron powder according to the mass ratio of 1: 1-1.5;
b. briquetting the ground powder;
c. putting the block-shaped materials into a heating furnace for high-temperature treatment, heating to 1000-1200 ℃, then preserving heat, and cooling to room temperature;
d. and taking out the blocky materials to carry out crushing and grinding to obtain the iron-containing coke powder.
In the step a, preferably, the mixture particles of the coke coal and the iron powder are ground to 60-80 μm, so that the contact area is increased, the reaction efficiency is improved, the ratio of the coke coal to the iron powder can enable the carbonization reaction to be sufficient, about 95% of Ti elements in the blast furnace slag are selectively enriched and grown around iron particles in a TiC form, and the Fe-TiC combination is obtained. And (c) briquetting the powder in the step (b), wherein the pressure is preferably not less than 10MPa, so that the coking coal and the iron powder form compact iron-containing coke to support the subsequent crushing into iron coke particles. And c, when high-temperature treatment is carried out in the step c, argon is introduced into the heating furnace for protection, so that the reaction of the iron powder and the coke with air is avoided, the flow of argon is about 1L/min, the heating speed and the cooling speed are preferably controlled to be 5-10 ℃/min, the heat preservation time after heating is not less than 2h, and the formation of the iron-containing coke is facilitated. And finally, in the step d, preferably crushing and grinding the blocky materials into iron coke particles with the particle size of 0.3-0.6 mm, so as to facilitate the subsequent mixing reaction with the blast furnace slag.
When the iron-containing coke and the titanium-containing blast furnace slag are used for carbonization reaction, the following process parameters are required to be controlled: in the step A, the grain size of the added titanium-containing blast furnace slag is preferably controlled to be 60-80 μm, so that the titanium-containing blast furnace slag can be conveniently and fully contacted and reacted with the iron-containing coke. And C, when the blocky materials are subjected to high-temperature treatment in the step C, introducing argon into the heating furnace for protection, so as to avoid the reaction of air and the iron-containing coke, wherein the flow of the argon is about 1L/min. The heating rate and the cooling rate are both 5-10 ℃/min, the heat preservation time after heating is not less than 4h, and the carbonization reaction and the selective enrichment and growth of Ti element around iron grains in a TiC form are facilitated. And finally, in order to meet the subsequent magnetic separation requirement, when the blocky material is ground in the step D, the blocky material needs to be ground until the grain diameter is less than 200-250 mu m and is equivalent to the average grain diameter of the Fe-TiC combination body about 230 mu m.
Finally, during magnetic separation, the magnetic field intensity of the magnetic field is preferably controlled to be 150-300 mT, the content of TiC in the fine slag obtained through separation can reach about 25%, and the recovery rate of Ti element reaches 80-90%.
