The traditional preparation process of fluozirconic acid is carried out in a reaction kettle, where zirconium oxide reacts with concentrated hot hydrofluoric acid. However, the use leads to high and equipment costs, severe environmental pollution, significant safety hazards. Moreover, purity original solution after dissolution low, phase composition complex. In this paper, method for controllable studied. This that using 99.8% sponge 8N medium concentration as raw materials under normal temperature pressure. optimal was determined experimentally 35% liquid-solid ratio 5 mL·g⁻¹. Under these conditions, HZrF5 content reached its maximum, thereby creating favorable conditions subsequent hydrometallurgical tetrafluoride (ZrF4), through hydrometallurgy. At same time, paper also conducts certain explorations on characterization solution.
