Embodiment

[0034] In one embodiment, the daily processing of raw ore is 600 tons, the tailings volume is 558.3 ​​tons, and the tailings concentration is 12%. Two cyclones, 48 ​​spreading chutes, and 24 4m 3 Sedimentation tank, 8 conical surfaces, 9 shakers, 4 flotation tanks.

[0035] In other embodiments, the scale can continue to be expanded to recover more tin concentrates.

[0036] If the concentration of tailings is high, it cannot flow uniformly in the spreading chute, and it is easy to form tailings accumulation. At this time, water can be added to reduce the concentration of tailings. In one embodiment, the tailings concentration is 10-15%, preferably 12%.

Abstract

Disclosed are a method and a system for recovering tailing resources. The system comprises a cyclone, a spreading chute, a conical surface, a flotation tank and a device. The cyclone is used for classifying tailings, the spreading chute is used for recovering the tailings and positioned on the downstream of the cyclone, a buffer tank is arranged between the spreading chute and the cyclone, the conical surface is used for enriching the tailings and positioned on the downstream of the spreading chute, a settling tank is arranged between the conical surface and the spreading chute, the top of the conical surface for enriching the tailings is provided with an automatic rotary tailing separator which is positioned between the settling tank and the conical surface for enriching the tailings, the flotation tank is used for concentrate flotation, the middle end of the flotation tank has a first gradient, the rear end of the flotation tank has a second gradient lower than the first gradient, and the device is used for containing concentrate. The method and the system have the advantages of distributing reasonableness, high recovery rate and obvious economic effects.

Description

technical field [0001] The invention relates to a method and system for recovering tailings resources, and is especially suitable for the recovery process of tin tailings, and is also suitable for the recovery and utilization of gravity separation tailings such as tungsten mines. Background technique [0002] Tin is a relatively scarce metal, which requires resource recycling to save resources and protect the environment. Tin ore is mined underground, which mainly recycles tin concentrate. The by-products include zinc concentrate, iron concentrate powder, and sulfur concentrate. The tin grade of the tailings discharged from the dressing plant is about 0.2%, which has the value of recycling. In the prior art, the layout of the recovery process of tin tailings resources is not reasonable enough, the recovery rate is not high, and the economic effect is poor. Contents of the invention [0003] The purpose of the present invention is to provide a recovery method and system fo...
