Abstract: <FONT face=Verdana>With high-speed development of China′s fluorine industry,fluorine resources would be rapidly exhausted.Therefore how to recover and utilize the abundant fluorine resources existing in phosphate rocks became more and more important.Status of fluorine resources and current utilization situation of fluorosilicic acid by-produced from phosphorus chemical industry in China were summarized,and production of anhydrous hydrogen fluoride (AHF) as the best utilization way of fluorosilicic acid was put forward by comparing market situation of various kinds of fluorine-based chemicals made from fluorosilicic acid.In addition,some patents on AHF at home and abroad and research achievements in production of AHF from by-produced fluorosilicic acid at Sichuan University were reviewed in detail.At last,some corresponding countermeasures and suggestions were put forward in order to solve the existing problems in production of AHF from fluorosilicic acid. </FONT>
