【 摘 要 】

Phosphogypsum (PG) is a radioactive industrial by-product produced in large quantities when processing phosphate ores into fertilizers. With rapid growth of high concentration phosphate and compound fertilizers production in China, PG production is increasing every year. Phosphogypsum is usually stored in such a way that it not only occupies a large piece of land, but also leads to environmental pollution. Utilization approaches of PG are put forward in this document in order to provide the scientific support for the effective utilization.
