In a sampling method according to the present invention, the coordinates (position information) of a sampling position of a sampling specimen (G) are generated randomly by a PC or other control unit (12) for a sampling position display device (10), and on the basis of the position information, laser light is used to display the sampling position on the sampling specimen (G), which constitutes a portion of material to be recycled. As a result, in increment sampling for determining the average quality, for example, the average valuable metal content, of a sampling specimen (G), it is possible to reliably eliminate arbitrariness resulting from the selection of a sampling position manually by an operator. |
