The invention provides a repeated stratifying, zoning-screening gravity concentration method. The gravity concentration method comprises the steps of minerals are ground; and the ground minerals are sorted by adopting gravity concentration equipment and are orderly discharged according to the same settling speed at the discharge end of the gravity concentration equipment, and the discharged materials are equally divided into n parts at the discharging end along a discharging belt, wherein n is not less than 4, and the n parts of the discharged materials are screened respectively so as to obtain high-grade concentrates, middlings and tailings. According to the gravity concentration method, by the adoption of the technical scheme, the concentrate grade can be high, the recovery rate can be high, operation can be convenient, and the conventional gravity concentration equipment can be used; and compared with screening and grading of the minerals without being subjected to gravity concentration treatment, the gravity concentration method has the advantage that the screening efficiency is higher by 30-70%.
