Gibson s method 4 is based on the principle that ammonium hydrogen fluoride effects the complete decomposition of beryl at a low temperature, even if the mineral is only coarsely ground. Much of the silica is volatilized as ammonium fluosilicate and the beryllium and aluminium converted first to fluorides, then sulfates. The former is separated by solution in (NH COs. [Pg.84]

Fluorine is usually recovered in the form of an aqueous solution of fluosilicic acid, H2S1F6. The concentration may be as high as 20%-25%. In some countries the fluosilicic acid is used directly for fluoridation of municipal water supplies to prevent tooth decay. The acid is shipped to various municipalities in rubber-lined rail-cars. Salts of fluosilicic acid, such as sodium, potassium, and ammonium fluosilicates, have various uses and can be readily produced from the acid. Sodium fluosilicate is... [Pg.340]
