Abstract
This article mainly discusses the issues related to the fate of fluorine in China's phosphorus chemical industry.This article introduces the reserves,production,and characteristics of phosphate ore in China,as well as the associated resources of phosphate ore and the current de-velopment status of phosphate chemical industry.This paper elaborated on the processing methods of phosphate ore,including wet process phos-phoric acid technology and hot process phosphoric acid technology,analyzed the fluorine resources in phosphorus chemical industry,including fluorine-containing ores and associated fluorine resources in nature.The focus was on discussing the fate of fluorine in phosphorus chemical in-dustry,taking wet process phosphoric acid technology as an example to analyze the flow of fluorine,and introducing the comprehensive utiliza-tion of fluorine resources associated with phosphate ore,including the preparation of hydrofluoric acid,artificial fluorite,and various fluoride salts.It is believed that China has made certain progress in the comprehensive utilization of fluorine resources associated with phosphate mines.In order to achieve sustainable development of the phosphate chemical industry,it is still necessary to enhance technological innovation and pro-mote industrial upgrading.关键词
