Abstract

283,187. Liljenroth, F. G. Jan. 8, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Manures.-Raw phosphates containing calcium phosphate are treated with acid to recover phosphoric acid, and the lime is converted by the addition of sulphate solution into calcium sulphate, which is separated with or without other insoluble matter from the phosphates and treated with ammonia and carbon dioxide to form ammonium sulpbate and calcium carbonate. The ammonium sulphate solution may be used to precipitate calcium from the solution obtained by treating raw phosphates with insufficient sulphuric acid or an acid with a soluble calcium salt, e.g. nitric acid, the solution finally being neutralized with ammonia and concentrated to form a mixed manure.
