Abstract The presence of impurities in phosphogypsum has long impeded its effective utilization, highlighting the need for energy-efficient and sustainable purification methods. This study proposes a novel purification strategy that synergistically combines pH regulation and micelle-assisted treatment to create an optimized microenvironment for impurity removal. Under mechanical grinding conditions, this approach enhances the rheological properties of the phosphogypsum slurries and facilitates the dissolution and removal of impurity ions. Experimental results demonstrate that the synergistic method achieves a remarkable 64.01% increase in whiteness while significantly reducing soluble phosphorus and fluoride content in a single-step process.
