Fluorspar

In 2005, most of the fourspar consumed in the United States was imported or purchased from the US National Defense Stockpile (NDS). For the year, the estimated annual production of fluorosilicic acid was 49 kt or about 86 kt of 92% flourspar equivalent. Prices increased due to reduced exports from China. For the coming years, flourspar supplies are expected to remain tight during the short term because of China's further restriction on flourspar exports.
