After grinding treatment, phosphogypsum can be widely applied in multiple fields to achieve resource utilization:

1. Cement Industry

Used as a cement retarder to replace natural gypsum, regulating cement setting time.

Applied in the co-production of sulfuric acid and cement, forming a circular economy.

2. Building Materials

Production of gypsum boards, gypsum blocks, gypsum mortar, etc., for wall and decorative materials.

Used as a cementitious material in the preparation of lightweight concrete and insulation materials.

3. Fertilizer Industry

Preparation of fertilizers such as ammonium sulfate and potassium sulfate, by recovering calcium and sulfur resources in phosphogypsum through chemical conversion processes (e.g., double decomposition reaction).

4. Chemical Raw Materials

Used as a raw material for producing other chemicals, such as calcium carbonate and calcium oxide.

5. Soil Improvement

Acts as an amendment for acidic soils, regulating soil pH and improving soil structure.

6. Roadbed Materials

Applied as roadbed filling in road construction to enhance roadbed stability.
