[PROBLEMS] To identify ore particles correctly even when ore particles agglomerate in powdered ore after flotation, and as a result, the degree of simple separation in the actual beneficiation process was reflected. A method of making a sample is provided. A method for producing a sample for mineral analysis having a powdered ore to be analyzed, the drying step of drying the powdered ore containing a plurality of ore particles obtained by flotation, and the ore by drying By mixing the resin granules with the dried ore containing aggregates in which the particles are agglomerated, and stirring the mixture in a mill, a crushing step for crushing the agglomerates, and ore by crushing the agglomerates A resin embedding step of embedding a powdered ore in which particles are dispersed with a thermosetting resin.
