摘要：
A cyclic preparation method including the following steps: a) boric acid or boric anhydride is added with hydrofluoric acid and then with potassium sulfate for reaction to generate potassium fluoborate; titanium-iron concentrate is added with hydrofluoric acid and then with potassium sulfate for reaction to generate potassium fluotitanate; B) the potassium fluoborate is mixed with the potassium fluotitanate, and the mixture reacts with aluminum to generate titanium boride and potassium cryolite; C) the potassium cryolite is sucked out and then fed into a rotary reaction kettle together with concentrated sulfuric acid, hydrogen fluoride gas as well as potassium sulfate and potassium aluminum sulfate are generated by reaction in the rotary reaction kettle, and the hydrogen fluoride gas is collected and then dissolved in water to obtain hydrofluoric acid aqueous solution; and D) the obtained hydrofluoric acid aqueous solution and potassium sulfate aqueous solution are recycled.
