Abstract

To provide a rock selection system capable of selecting a rock, without being based on experience or the like in the selection of the rock containing ore.SOLUTION: The rock selection system includes a supply device, an imaging apparatus, an identification device, and a selection device. The supply device supplies the rock containing the ore. The imaging apparatus images the supplied rock. The identification device identifies the type of the rock by using the classification model of the rock learned by using an image obtained from the imaging apparatus. The selection device selects the type predetermined on the basis of the identified type of the rock.SELECTED DRAWING: Figure 1
