Description
Technical field
The utility model relates to a kind of ore concentration of bauxite circular water treating system.
Background technology
China's ore concentration of bauxite technology starts from the seventies in last century, first bauxite flotation commerical test was carried out at the Xiao Guan of China Changcheng Aluminium Industry Co aluminium ore in 2000, and first industrial production line put into effect in middle aluminium Central Region branch company grafting alumina producing flow process in 2002.Bauxite ore production technology aspect, two stages have been experienced: the phase I, the ore concentration of bauxite technology is take grafting alumina producing flow process as the basis, wish that take middle aluminium Central Region branch company ore dressing engineering, middle aluminium Henan branch company ore dressing plant, east Sanmenxia Gorge Aluminum ore dressing engineering is as representative, adopted one section overflow mill to add the selective milling flow process of two sections classifications, two sections mill grinding flowsheets, present three ore dressing plants are all producing.Second stage, ore concentration of bauxite technology also are as the basis, take Cayman, Henan Aluminum, Henan Huiyuan Aluminum as representative take grafting alumina producing flow process.Cayman, Henan Aluminum ore grinding uses two sections mill grinding flowsheets, the microvesicle mineralising, roughly select, selected, scan parallel-connection flow.The shallow slot gradient floatation is selected in the ore dressing of Henan Huiyuan Aluminum, and the mine tailing coarse sand carries out secondary grinding and flotation.At present, Cayman, Henan Aluminum, Henan Huiyuan Aluminum ore concentration of bauxite are also being produced.The ore concentration of bauxite technology all is as basis, a most important factor take grafting alumina producing flow process no matter be phase I or second stage, be exactly in the employed ore concentration of bauxite technology, will constantly replenish new water and clean flow process, backwater can't independently digest, and causes the backwater swell-belly.Ore concentration of bauxite backwater composition is very complicated, contains a large amount of mine tailings, concentrate, collecting agent, sodium carbonate, calgon, flocculant, foaming agent, also contains a certain amount of other additive, inorganic salts etc.Generally speaking, process 1 ton of raw ore, roughly need to efflux 1.5 tons of water, produce 200000 tons of flotation concentrates per year and process day by day 1000 tons of raw ores, day roughly needs to efflux 1500 tons of water, so a large amount of outer drainings, be exactly that grafting is in the alumina producing flow process, also be very heavy thing, this has influence on the safety and environment protection of company, more is related to the sustainable development of enterprise.At present, the comprehensive utilization technique level of research and the ore concentration of bauxite backwater of practical application is, adds the flocculant sedimentation separation, and supernatant liquor water is got back to system flow.Such way is processed very not thorough, causes and can only partially recycledly utilize the ore concentration of bauxite backwater, therefore, is independent of the alumina producing flow process, recycles the backwater of ore concentration of bauxite total system fully, is urgent problem.
Summary of the invention
For above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of ore concentration of bauxite circular water treating system, can effectively solve in the existing ore concentration of bauxite recycling water utilization process recycling water utilization rate low, and outer draining causes the problem of environmental pollution.
Originally be that the technical scheme that utility model solves is, comprise circulating water pool, flotation device and filter press, the water source links to each other with ion-exchanger, ion-exchanger links to each other with the import of ionized water tank, the outlet of ionized water tank links to each other with the import of flocculating agent formulation groove with the beneficiation reagent configured slot respectively, the outlet of flocculating agent formulation groove links to each other with the import of concentrate subsider with the mine tailing subsider respectively, the outlet of beneficiation reagent configured slot links to each other with the flotation device import, the concentrate outlet of flotation device is deposited the pond import with concentrate and is linked to each other, concentrate is deposited the pond outlet and is linked to each other with the import of concentrate subsider, the outlet of concentrate subsider links to each other with the first filter press import, the outlet of the first filter press links to each other with processing forebay import, the mine tailing outlet of flotation device is deposited the pond import with mine tailing and is linked to each other, mine tailing is deposited the pond outlet and is linked to each other with the import of mine tailing subsider, the outlet of mine tailing subsider links to each other with the second filter press import, the outlet of the second filter press links to each other with processing forebay import, processing the forebay outlet links to each other with the gas-liquid mixed pump inlet, plasma generator links to each other with the gas-liquid mixed pump inlet, the gas-liquid mixed pump discharge links to each other with the import of gas liquid reaction pipe, the outlet of gas liquid reaction pipe links to each other with the circulating water pool import, circulating water pool outlet respectively with the concentrate subsider, the mine tailing subsider links to each other with the import of grid grinding machine, and the outlet of grid grinding machine links to each other with the flotation device import.
The utility model novel structure is unique, distributes rationally, establishes one's own system, and is easy to use, and essence, tailings dewatering are effective, and system operates steadily, and has realized that system water 100% recycles, and without outer draining, has good society and economic benefit.
