The present invention discloses a silicon reclamation apparatus with which a large amount of silicon can be easily reclaimed from a waste slurry. The silicon reclamation apparatus comprises: a solid-liquid separation part in which either a waste slurry discharged from a cutting device or polishing device in which a slurry comprising abrasive grains and a coolant is used for silicon cutting or polishing or a waste slurry concentrate obtained by concentrating the waste slurry is subjected to solid-liquid separation to obtain solid substances for silicon recovery; a washing part in which the solid substances for silicon recovery are washed with an organic solvent; and a classification part in which the solid substances for silicon recovery after the washing are classified to obtain a silicon-containing powder having a higher silicon content than before the classification.
