Patent FR-363909-A (FR)
IPC: C01F7/0673
Filed: 1906-03-07
Granted: 1906-08-10
Abstract: Aluminium phosphate is dissolved in boiling caustic alkali, for example, caustic soda, the solution is cooled, say to 15 DEG  C., to crystallize alkali phosphate, and the mother liquor is employed with fresh caustic alkali to dissolve a further quantity of aluminium phosphate.  This operation is repeated several times, the alkali phosphate becoming progressively more insoluble as the concentration of the alkali aluminate increases, until the solution reaches a certain concentration, when, after precipitating residual phosphoric acid with lime or other suitable metal oxide, it is treated in known manner for the recovery of alumina.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subjectmatter:--The solution obtained by dissolving aluminium phosphate in caustic alkali is treated with organic or inorganic bases forming insoluble phosphates, and the alkali liquors filtered therefrom are returned for further decomposition.  Thus, the solution may be precipitated with baryta, and the barium phosphate treated with sulphuric acid. Barium sulphate filtered from the phosphoric acid is converted to barium sulphide, and this with hydrochloric acid to barium chloride.  Hydrogen sulphide evolved is converted to sulphuric acid for re-use, and the barium chloride is treated with sodium nitrate to produce barium nitrate, from which baryta is obtained. Sodium chloride produced is reacted with sulphuric acid to produce hydrochloric acid and sodium sulphate for re-use.  In another example, the alkali aluminate-phosphate solution is treated with silver nitrate.  Silver phosphate, sodium nitrate, and alumina are deposited, residual soda solution being returned to the leaching. The precipitate is treated with ammonia producing soluble silver-ammonium phosphate, (subsequently decomposing), and a residue of alumina.  The silver phosphate is treated with hydrochloric acid to give phosphoric acid and silver chloride, which latter is decomposed to silver and chlorine.  The silver is dissolved in nitric acid, and the chlorine converted to hydrochloric acid, both products being re-used in the process. Sodium nitrate produced in the process may be converted to potassium nitrate, or may serve for the oxidation of sulphur dioxide produced during the decomposition of sodium-aluminium phosphate by heat (?), or it may be reacted with the barium chloride obtained in the previous example to produce barium nitrate and sodium chloride.  This subject-matter does not appear in the Specification as accepted.
