Provided is a comprehensive recovery method for gold flotation tailings, comprising the following steps: the flotation tailings are classified by a hydrocyclone; coarse grains enter a vibrating spiral chute for sorting, the ore concentrate from the vibrating spiral chute enters a shaking table for further sorting, and the middling ore from the vibrating spiral chute returns to the vibrating spiral chute for re-sorting; the ore concentrate from the shaking table is a gold concentrate, the middling ore from the shaking table returns to the vibrating spiral chute for re-sorting, and the tailings from the shaking table undergo a magnetic separation; the ore concentrate from the magnetic separation is an iron concentrate, the fine grain overflow from the hydrocyclone, the tailings from the vibrating spiral chute and the tailings from the magnetic separation converge together to enter a tailing pressure filtration system, and the tailing backwater returns for recycling. Moreover, also provided is a device for realizing the above-mentioned method, wherein the device consists of a hydrocyclone, a vibrating spiral chute, a shaking table, a magnetic separator and a concentration system. The gold recovery is improved and the cost is reduced by using the method and the device. |
