On January 13, the public consultation on the environmental impact assessment for the (modified) Phosphorus-Fluorine New Materials Mineralization Integrated Industrial Park project of Guizhou Sierte New Energy Materials Technology Co., Ltd. was made publicly available for the first time on relevant websites. The details of the project 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 largely unchanged.
