An annual output of 10,000 tons of anhydrous hydrogen fluoride project was established in Fujian Fufu Lantian Company. On January 12th, the project started in the Qiyang Industrial Park of Shanghang County. This project is the Fufu Zijin Wet-Process Phosphoric Acid Supporting Project. It is also the second project in the world to recycle fluorine resources for the processing of hydrogen fluoride from phosphate rock. The total investment is approximately 170 million yuan. It is planned to be completed and put into operation in August 2012. The project can not only digest fluorosilicic acid, a by-product of Qifu Zijin, but also recycle fluorosilicic acid, a by-product of the fluorspar hydrogen fluoride plant, breaking the tradition that HF ​​must use fluorspar and open up a new source of hydrogen fluoride feedstock. .
