Recently, the second public announcement of the environmental impact assessment report for the Phosphorus-Fluorine New Materials Mineralization Integration Industrial Park project (with modifications) of Guizhou Sierte New Energy Materials Technology Co., Ltd. was made. The project details are as follows: Project name: Phosphorus-Fluorine New Materials Mineralization Integrated Industrial Park Project (Revision) ； Construction unit: Guizhou Sierte New Energy Materials Technology Co., Ltd ； Total investment: 1,724.48 million yuan ； Construction location: Daba Village, Yongwen Town, Kaiyang County, Guiyang City ； Construction content and scale: Construct a 100,000-ton/year industrial-grade phosphoric acid (85% H3PO4) plant and a 50,000-ton/year potassium dihydrogen phosphate plant; simultaneously build a 650,000-ton/year phosphate rock pretreatment (including magnesium removal) plant, a 400,000-ton/year sulfur-based acid production plant, and a 150,000-ton/year wet-process phosphoric acid (equivalent to 100% P2O5) production and purification plant ； By-product comprehensive utilization facility (10,000 tons/year of sodium fluosilicate, 50,000 tons/year of phosphorus-based fire extinguishing agents, 40,000 tons/year of water-soluble fertilizers, and harmless treatment of 800,000 tons/year of phosphogypsum and demagnified slag). The main change in this revision is that the project’s wastewater, instead of being reused after treatment at the on-site sewage treatment plant, will now be discharged into the Yangshui River after meeting the required treatment standards; all other aspects remain essentially unchanged.
