Abstract
135,545. Dutt, E. E., and Dutt, P. C. Oct. 18, 1918. Drawings to Specification. Potassium sulphate.-Potassium fluoride and silica are heated to 800‹ C. in one of the revolving furnaces described in Specification 124,544 whilst sulphur dioxide and steam are passed in. Silicon tetrafluoride is evolved, leaving a residue from. which potassium sulphate is obtained by lixiviation. The silicon tetrafluoride its introduced, along with water vapour, into the second revolving furnace, where they react with a potash-hearing silicate rock such as feldspar, in the manner described in Specification 133,474, to produce potassium fluoride.
