Abstract
The recovering process from non-ferrous metal tailings includes the steps of digging pit, injecting water, stirring, extracting tailing pulp, ball milling, floating and exhausting and utilizing dregs. The present invention is suitable for recovering mineral material from low grade non-ferrous metal tailings, especially from the tailings of closed mine.
Description
Technical field
The invention belongs to the waste recovery field, relate to the mine tailing re-separating process, relate to a kind of re-separating process of non-ferro metals debris particularly.
Background technology
The copper mine of China, plumbous zinc ore, gold mine, silver ore exploitation early, the river course is injected in the discharging that during it is produced there is the mine tailing in ore dressing plant, majority is taked to build in the river course and is built tailings reservoir for piling, because recovery rate in ore-dressing is lower, contains callable kish resource in the mine tailing.At present existing many old mines are closed because of source of crude is deficient, and the ore dressing plant also stops production, and cause preparation equipment idle.Because mineral resources can not be regenerated, the development and use of mine tailing have become the urgent task of these ore deposit factories.
Existing part mine tailing directly is used as building material by people, makes building block or cement baking, and valuable metal tailings resource is not reasonably developed.
Summary of the invention
The inventor is through social investigation, find that existing nonferrous metal mine exists the problems referred to above, at the present situation of the non-ferro metals debris of being sunk into sleep in a large number, purpose is to provide a kind of re-separating process of non-ferro metals debris, so that a large amount of non-ferro metals debris is developed.
For realizing above-mentioned task, the technical solution used in the present invention is the re-separating process of a kind of non-ferro metals debris of design, and its technological process is: dig pit, and---water filling---is stirred---extracting mine tailing slurry---the new tailings discharging utilization of ball milling---flotation---.
Wherein dig pit, excavate shallow mine tailing hole at the mine tailing upper epidermis successively in upstream, mine tailing storehouse, middle reaches, erection bracket on the hole is installed mixer, and mortar pump is installed; Water filling adds water in the hole; Stir, stir the mine tailing hole, make mine tailing pulp in the hole with mixer or water under high pressure; Extracting mine tailing slurry is sent into ore dressing plant ball mill with above-mentioned mine tailing slurry by pipeline with mortar pump; Ball milling is with ore dressing plant ball mill fine grinding mine tailing slurry; Flotation is sent the slurry of the mine tailing after the fine grinding into the flotation device flotation; New tailings discharging utilization enters new mine tailing storehouse with the new mine tailing after the flotation, and new mine tailing can be used as the raw material of construction material.
The present invention takes above technical measures, existing mine tailing is returned choosing handle, and has following remarkable advantage:
Employing is digged pit on the top layer, storehouse, and construction is convenient to mechanical personnel and is entered the storehouse easily, and construction is installed, because the mine tailing accumulation is dark in the mine tailing storehouse, area is big, and middle lower floor can avoid with excavator or civilian worker's difficult like marshland; Save again simultaneously outside the storehouse, to build and stir ground; Take in the order of upstream, mine tailing storehouse, middle reaches recovery successively, because mine tailing flows in the process in mine tailing storehouse, the mine tailing grain is more in the upstream enrichment, can improve the processing tailings grade, reduce treating capacity and can improve the rate of recovery again, improve the grade of tail concentrate, again entail dangers to safety not; The present invention can make full use of idle ore dressing plant capital equipment, does not need newly-built ore dressing plant; Mine tailing of the present invention had both been peeled off attached to the outmoded medicine on the mine tailing grain through ball milling, argillization thing and oxide layer, again fine grinding the mine tailing grain, the metal flotation that helps in the mine tailing is reclaimed.It is little that the present invention has investment, is convenient to enterprise's exploitation and reclaims, and makes the non-ferro metals debris of being sunk into sleep in a large number obtain comprehensive utilization through handling.
Description of drawings
Fig. 1 represents the re-separating process process chart of non-ferro metals debris of the present invention.
The specific embodiment
Further specify the concrete steps of technological process of the re-separating process of non-ferro metals debris of the present invention in conjunction with the accompanying drawings and embodiments, its feature and advantage are clearer.
The embodiment of the re-separating process of non-ferro metals debris of the present invention, stacking bore 2m of top layer, storehouse excavation of upstream, mine tailing storehouse for many years, the shallow mine tailing of dark 1.5m hole, solid frame support on the hole, the rotating shaft of vertical mixer is erected on the support by screw rod, deepen to regulate the height of mixer along with the mine tailing hole, install 4 " mortar pump; water filling in the mine tailing hole; the enough mixer stirrings of water injection rate energy mine tailing is cheated and be made mine tailing be pulpous state, washes away mine tailing with water under high pressure when running into undermixing, with mortar pump the mine tailing slurry is delivered to day from the interior extraction in mine tailing hole by conveyance conduit and handles the further fine grinding of 200T ore dressing plant ball mill; the slurry of the mine tailing after the fine grinding is sent into flotation cell, flotation; Mine tailing enters the technology behind the ore dressing plant, comprises ball milling, floating agent, the mine tailing concentrate filters, and new tailings discharging, all the technology with traditional ore dressing plant is the same, after new mine tailing reclaims through processing, can be used as construction material, brickmaking, system cement etc. can be as storing up new mine tailing after handle in old mine tailing storehouse, saving takies newly, does not need newly-built mine tailing storehouse.
