The invention discloses a mineral spiral ore feeding barrel. The mineral spiral ore feeding barrel comprises an ore feeding barrel body, wherein an ore feeding hole is formed in the upper part of the ore feeding barrel body and a discharging hole is formed in the lower part of the ore feeding barrel body; the ore feeding barrel body is internally provided with a plurality of left and right spiral flow guide grooves; the discharging hole is a tapered outlet with a rotational flow hole; the left and right spiral flow guide grooves are spirally wound on a stand column; the upper end of the stand column is aligned to the ore feeding hole; the upper ends of the left and right spiral flow guide grooves are located below the ore feeding hole; an outlet end of the left spiral flow guide groove and the outlet end of the right spiral flow guide groove are located on the same horizontal plane and front surfaces are opposite; and the stand column is fixedly connected with the ore feeding barrel body through a supporting part. By reasonable arrangement and an optimized design, noises can be effectively reduced and the life cycle of the ore feeding barrel is prolonged when the spiral ore feeding barrel is used for spirally feeding; and the centrifugal force of slurry is relatively small and the slurry is relatively uniformly distributed in a washing barrel, so that a magnetic flocculation phenomenon in the slurry is effectively solved and the washing efficiency is improved.
