Phosphogypsum regeneration resource utilization
Phosphogypsum is a solid waste, and when used instead of natural gypsum to prepare sulfoaluminate cement, a large amount of phosphogypsum is required. A certain ratio of phosphogypsum to bauxite and limestone is used to burn sulfoaluminate cement to reduce the cost of pretreatment, and the harmful impurities in phosphogypsum can be directly converted into beneficial clinker minerals, making this technology highly innovative.
