specific Embodiment 1

[0025] Such as Figure 1-6 As shown, a single floating tank test was carried out on zinc tailings in a dressing plant, and two sets of suspension ladder self-flow impact foaming tailings recovery devices were prepared. Each device included a tailings slurry pool 1 for containing zinc tailings slurry 8 , pulp pipeline 2, unpowered floating tank 3, foam tunnel 5, discharge pipe 6, the tailings pulp pool 1 is connected to the first pulp port 21 of the unpowered floating tank 3 through the pulp pipeline 2, and the unpowered floating tank 3 has a Block the zinc tailings slurry 8 to cause it to oscillate to form the baffle 31 of the foam 7, the foam outlet 4 of the floating tank for discharging the foam 7, the foam outlet 4 of the floating tank is connected with the foam corridor 5, and the first stage of the unpowered floating tank 3 The second pulp port 22 is connected to the first pulp port 21 of the second-stage non-powered floating tank 3 through the pulp pipeline 2 , and the s...

specific Embodiment 2

[0037] Such as Figure 1-5 As shown in , 7, the industrial test of floating tank-screening combined process was carried out on the zinc tailings of a certain dressing plant. According to the particle size of the zinc tailings, the zinc mineral distribution rate is basically above 0.15mm, and the zinc metal distribution rate of the zinc tailings is 68.66%. , due to the similar buoyancy of coarse-grained zinc minerals and fine-grained pyrite, the floating tank foam is used to enter the 0.22mm mesh vibrating fine screen, the product on the screen is low-grade zinc concentrate, and the product under the screen is combined with the tailings in the floating tank As floating zinc tailings.

[0038] Prepare 4 sets of suspension ladder self-flow impact foaming tailings recycling devices, a set of devices includes tailings slurry pool 1 for containing zinc tailings slurry 8, slurry pipeline 2, unpowered floating tank 3, foam tunnel 5, discharge Pipe 6, the tailings slurry pool 1 is con...

Abstract

The invention discloses suspension ladder gravity flow impact foaming mine tailing recycling technology, and a device thereof. The device comprises a mine tailing ore pulp tank, an ore pulp pipeline,an unpowered floating tank, a foam path, and a discharge pipe; the mine tailing ore pulp tank is connected with a first ore pulp opening of the unpowered floating tank through the ore pulp pipeline; the unpowered floating tank is provided with a blocking plate which is used for blocking zinc mine tailing ore pulp and forming of foam through agitating overturning, and a floating tank foam outlet used for discharging foam. The suspension ladder gravity flow impact foaming mine tailing recycling technology is capable of solving problems in the prior art that in conventional flotation selection recycling of zinc metal in mine tailing, recycling process is complex, and cost is high; production technology process of recycling of zinc metal in mine tailing is simplified; excellent practical operation effect is achieved; operation is convenient; full ore pulp foaming is ensured; zinc metal recovery rate is increased; production cost is reduced; low cost mine tailing zinc metal recycling is realized; technology process is simple; using condition requirement is low; and zinc metal recovery rate is high.

Description

technical field [0001] The invention relates to the technical field of tailing recovery technology and devices. Background technique [0002] At present, the main method of recovering zinc metal in the tailings of the dressing plant is flotation. The flotation method is based on the addition of collectors, activators, surfactants and other agents, which are introduced into the air for stirring, and then use the difference in floatability of zinc and pyrite in the tailings to separate zinc metal, but Due to the complex structure of flotation equipment and high requirements for use conditions, the process of sorting zinc in tailings by this method is complicated, the dosage of chemicals is large, and the production cost is high, resulting in no economic benefits for the recovery of zinc metal in tailings. [0003] In recent years, domestic patent databases have disclosed some similar technical reports on methods for recovering lead-zinc minerals from high-sulfur lead-zinc min...
