PROBLEM TO BE SOLVED: To provide a method for producing a coating particle composition, capable easily conferring coating performance of excellent leaching preventiveness on fine powder as the core material even with a particle size of <=50 μm and high in production efficiency as well, and to obtain a coated granular composition by the above method. SOLUTION: This method for producing a coating particle composition comprises the following two processes: (A) a core material comprising fine powder <=50 μm in particle size is granulated using a substance sparingly soluble in water at normal temperatures, and (B) the resulting granulated product is coated with fat-and-oil. The other objective coating particle composition obtained by the above method is provided with a layer of the substance sparingly soluble in water at normal temperatures on the whole surrounding surface of a core material and a fat-and-oil layer outside the above layer. |
