| titleOfInvention | Production of alkali metal products from alkali metal fluosilicate |
| abstract | Alkali metal-containing salt products selected from the group consisting of alkali metal dihydrogen phosphate, alkali metal sulfate, alkali metal nitrate, and mixtures thereof, together with alkaline earth metal fluoride, are produced from alkali metal fluosilicate by the steps of: (a) reacting alkali metal fluosilicate with alkaline earth metal ion in an aqueous solution to form alkali metal hydroxide and solid alkaline earth metal fluoride with SiO2; (b) separating the solid alkaline earth metal fluoride and SiO2 and recovering as useful products; (c) reacting the remaining alkali metal hydroxide solution with a mineral acid selected from the group consisting of phosphoric acid, sulfuric acid, nitric acid, and mixtures thereof, at a temperature in the range of about 30 DEG -100 DEG C. until the reaction is complete; and (d) recovering the alkali metal-containing product. Also provided by this invention is a continuous system for conducting this reaction whereby mother liquors may be recycled and the acid reused in the process, and wherein mineral acid is recovered from which anhydrous HCl can be produced. |
