Impurity removal device for ore

The utility model relates to the technical field of ore impurity removal, in particular to an ore impurity removal device which comprises a conveying mechanism, an impurity removal mechanism is arranged on the upper side of the conveying mechanism and comprises a supporting column, the upper end of the supporting column is rotationally connected with a roller through a bearing, one end of the roller is in key connection with a driven wheel, and a plurality of claw teeth are welded to the outer ring of the roller. A collecting box is arranged on the rear side of the roller; the impurity removing device has the beneficial effects that by arranging the impurity removing mechanism, when a conveying belt drives ore on the surface to move to the lower side of claw teeth, a driving assembly drives a roller to rotate through a driven wheel, the roller drives the claw teeth on the outer ring to rotate, the claw teeth rake and grab the ore on the lower side, impurities doped in the ore are raked out, and the raked impu
