A Process of Granulating Calcium Cyanide to render it suitable for use as a Fertilizer

Calcium cyanamide is granulated for use as a manure by mixing the material with a solution of a silicate, preferably potassium silicate, drying, and crushing to granular form. The quantity of potassium silicate employed may be sufficient to secure the granulation, or may be greater so as to produce...

Summary:Calcium cyanamide is granulated for use as a manure by mixing the material with a solution of a silicate, preferably potassium silicate, drying, and crushing to granular form. The quantity of potassium silicate employed may be sufficient to secure the granulation, or may be greater so as to produce a manure containing a desired content of potash. A complete fertilizer may be produced by adding phosphatic material such as bone ash or phosphatic slag, but not superphosphate. 135,847. Saves, P. M. T. Nov. 26, 1918, [Convention date]. Manures.-Calcium cyanamide is granulated for use as a manure by mixing the material with a solution of a silicate, preferably potassium silicate, drying, and crushing to granular form.
