Research on the mechanism of P and F in phosphogypsum stabilized by humic acid synergized with group metallic triad-based curing agent

Key Points

• The aim is to develop a cost-effective method to stabilize high levels of soluble phosphorus and fluoride in phosphogypsum.
• Propose a stabilization strategy using humic acid and inorganic curing agents.
• Focus on lowering environmental risks associated with phosphogypsum.
• Demonstrates effectiveness in reducing soluble phosphorus levels.
• Successfully lowers soluble fluoride concentrations.
• Indicates potential for environmental improvement.
