C05B13/02—Fertilisers produced by pyrogenic processes from phosphatic materials from rock phosphates
Abstract
In preparing fertilizers by mixing calcined phosphates with one or more potassium salts, the separation of the components is prevented by incorporating small amounts of an oil or grease with one or other or both of the components or with the mixture, Potassium sulphate or technical potassium chloride are the potassium salts referred to. A mineral oil is a suitable oil. The Specification as open to inspection under Sect. 91 comprises also the employment of fats, petroleum jelly, mixtures of solid and liquid paraffins and oleaginous distillation residues. This subject-matter does not appear in the Specification as accepted.
