AI Technical Summary
Existing phosphogypsum crystallization processes suffer from low conversion rates, long reaction times, and poor product quality, making it difficult to achieve high-efficiency, low-consumption, and environmentally friendly high-value-added utilization.
A biological-inorganic inducing agent coupling method was adopted. After calcium oxide pretreatment, inorganic inducing agents such as lysine and calcium formate were added to regulate the crystal nucleation and growth of phosphogypsum, improve the crystal transformation rate and conversion rate, and improve the crystal morphology.
It significantly improved the crystallization rate and conversion rate of phosphogypsum, shortened the reaction cycle, improved product quality, and realized the efficient and low-consumption resource utilization of phosphogypsum.
