Background technology
In a variety of different nonferrous metal mines, concentrate, chats, the tailing of ore dressing generation contain more high-grade iron and zinc The different non-ferrous metals and rare precious metal such as lead bronze tin indium cadmium bismuth antimony germanium thallium gallium gold and silver, in the row such as non-ferrous metal and relieving haperacidity chemical industry Industry, non-ferrous metals smelting works and various chemical plant, the dedusting ash of processing factory (such as zinc-plated factory, plating nickel chromium triangle factory, sulfuric acid plant), sludge Also contain a certain amount of iron (generally being differed 10~60%) with various metallurgical slags, rotary kiln scum, processing waste residue, red mud etc. And/or various non-ferrous metals and the rare precious metal such as zinc lead bronze tin indium cadmium bismuth antimony germanium thallium gallium gold and silver nickel chromium triangle;In steel and ferroalloy etc. Metallurgy industry, the equipment such as the smelting furnaces such as blast furnace, steelmaking converter, electric furnace, ferro-alloy furnace and sintering, kiln, machine also will produce when producing The industrial residues such as non-ferrous metals element dust dedusting ash, the sludge such as a large amount of carbon containing and/or iron content zincy lead potassium sodium chlorine nickel chromium triangle are useless Material, if the sintering being incorporated as ferrous material before iron uses, the harmful elements such as these zincy lead potassium sodium chlorine enter blast furnace, will be tight Ghost image rings blast furnace and normally produces.These waste materials of the industry such as coloured, steel are powder-material, mud, generally use wet method point mostly It is various coloured that iron and zinc lead etc. are carried out from, flotation, Webster stove, fuming furnace, rotary kiln, rotary hearth furnace, shaft furnace, Circulation fluidized-bed furnace etc. The processing and recycling of the waste material of metallics, that there are equipment investments is big for these methods, operating cost is high, of high cost, iron and slag etc. Do not detach or detach halfway problem, there is also reagent consumptions big, the secondary dirt of waste water and dregs of wet-leaching method, floatation Contaminate environmental issue.However, in converter (including electric furnace etc.) STEELMAKING PRODUCTION of steel plant, will produce large numbers of containing iron oxide (with FeO, Fe2O3Based on) and more metal abrasive grit high alkalinity (high calcium CaO, high magnesium MgO) molten steel slag, fusing point is high, flowing Property it is poor, slag sluicing system is poor, slightly cooling is that solidification at once is not flowed, and wraps up a large amount of metal abrasive grits in slag, full iron generally 25~ 30% or more, basicity is mostly 2.8 or more, and high reaches 4.0, and temperature is also up to 1600 DEG C or more, each steel mill's generally use Heat dials method, is connect away the molten steel slag that converter is poured out with slag pan, is transferred to, is fetched water cold with carborne to slag processing place But, residual steel of the size block with slag is sucked out, is selected with crushing-magnetic selection method using the methods of electromagnet sucker by a large amount of steam of emerging Go out the metallic iron carried secretly in steel-making slag powder.Preferable big steel mill is fetched water hot bored, slag water after cooling in the bored case of heat using heat bored processing Change explosion.After recycling metallic iron processing, clinker, steel-making slag powder containing part metals abrasive grit and iron oxide composition, tail mud are taken out. Due to the discharge of slag interruption, easily solidification, iron content, all it is difficult to realize using water quenching or wind quenching, steelmaking converter dephosphorization, slag is phosphorous Height constrains slag recycling inside steel mill.Currently, each steel mill carries out cold conditions processing after slag cooling, all exist Technique is coarse, and ferro element difficult separation and recycling, the rate of recovery are low, and occupied ground is big, and get up steam airborne dust, and environment is poor, uncomfortable The environmental requirement that iron and steel enterprise is increasingly stringenter, high temperature thermal resource is answered to waste, be not utilized.
Inside coloured industry, these iron content and/or zincy lead to generations such as smeltings are (below by iron content and/or containing zinc Lead is referred to as iron content zincy lead) the waste material pyrogenic attack recycling of the metals such as copper and tin, to volatile zinc lead and other elements to restore cigarette Based on change method, to elements such as not volatile copper based on copper matte regulus absorption method, etc..These processing methods, to recycle high price Coloured and rare precious metal as the main purpose, then exist in the form of aoxidizing scum as inexpensive substance to ferro element therein, Slag is often abandoned it, iron not recycles.Non-ferrous smelt enterprise disperses, and the colored waste ingredient of discharge is miscellaneous, and pyrogenic attack heating is high Warm melting, its processing cost of consumption amount of heat is high, and recovering effect is poor, is forced mostly using wet-leaching processing recycling.In steel The industries such as iron and chemical industry, a large amount of iron containing sludge are in muddy, and iron content dedusting ash granularity is extremely fine, the useful member such as iron contained therein Plain quality is also irregular, some are also considered as the substances such as the zinc lead of harmful element containing the more steel industry in part, it is difficult to It utilizes, or even is considered as rubbish and abandons everywhere, pollute environment.
In steel industry, many researchs have been done to the processing of the lower converter slag of this value ratio.Chinese patent application Numbers 201610833748.9《A method of improving slag iron component recovery》, one kind is disclosed by toppling over slag in converter While modification agent is added, pouring into cinder ladle impact stirring using high-temperature fusion slag carries out certain modifications reactions, to be more convenient for Magnetic separation recovery after slag processing, the rate of recovery of ferro element when improving magnetic separation.Since the time of slagging tap is especially short, interruption, reaction Effect is poor, it is obvious that the rate of recovery of ferro element when these methods only improve magnetic separation slag iron to a certain extent, it is existing with each steel mill Modern slag cooling magnetic separation processing has no much differences, and pollution environment pours into cinder ladle modification there is no changing, in high-temperature fusion slag When processing, thick smoke of even more emerging, slag boiling are general relatively difficult to achieve in steel-making work area workshop.Slag produced from steel-smelting value compared with Low, cold conditions processing is really simple, but its useful resources and high temperature heat do not utilize, if only handling single steel under hot Slag is also faced with technique and a series of problems economically, and to the processing of slag, there has been no big breakthroughs at present.
《It is Chinese metallurgical》8 phases of volume 21《The recycling new approaches of iron and phosphorus are recycled in slag simultaneously》, it is contemplated to one Kind recycles iron phosphorus new approaches in slag in an ad hoc converter specifically for dephosphorized slag, by top blast oxygen bottom blowing stirring, converts Enter the phosphorus that restores in carbon saturation molten iron rich absorbent slag, and by reducing viscosity coefficient of dross after modification, enable iron phosphorus with Slag is smoothly detached, to recycle more phosphor resources.But it is practical in steelmaking converter area, then to set a block converter salvage value very low Slag, shunt for pneumatic steelmaking it is blast-melted come handle converter smelting discharge slag, first do not say molten iron shunting reduce The production scale of steel-making, technology arrangement and organization of production and stove and stove can be reduced, there is very greatly per stove with being connected per stove Problem, converter often fall a clinker stove under slag, be transported to stokehold platform by slag be blended into processing converter, the iron making of handling molten iron, with And the discharge trend etc. of the iron, slag after the stove that often blows of itself, discontinuous by this pneumatic steelmaking smelter of stove blowing The compact anxiety of skill feature (adds steel scrap, hot metal charging, lower rifle oxygen blast blowing, thermometric to see tapping, nitrogen flushing slag splashing one after sample, stove A smelting cycle only has short dozens of minutes, and converter is overturn back and forth, driving is shuttled after the stove of stokehold) Converter before, then Add a converter for handling the slag poured out to intersect therewith operation, almost without the possibility of realization, does not also see ad hoc turn at present Stove handles the engineering example of phosphorous slag, and converter oxygen top blown is easily formed oxidizing atmosphere and is not easy to be formed by force also Primordial Qi Atmosphere.Moreover the molten iron for being originally used for steel-making is diverted to processing slag and absorbs enriched phosphorus, becomes phosphorous pig, is molten iron The big still molten iron of benefit for becoming steel becomes the problem of phosphorous pig benefit is big and one need of steel mill are weighed, and therefore, this one Imagination is still difficult to carry out, meanwhile, this imagination is also limited to only handle single converter slag, it is expected that recycling therein few Iron and phosphor resource.
Chinese Patent Application No. 201611133558.2《A kind of method of slag metallurgy melting also original production》, disclose one The method of kind slag metallurgy melting also original production, the slag (iron-holder is less than 1%) of the molten steel slag of steel-making or blast furnace is added In one cool-bag, or addition one can carry out slag bath processing in electrically heated melting reaction device, pass through three necessary items Part:1. alkalinity or acid material is added to adjust slag basicity, fuel and Electric heating temperature raising is 2. added or chalybeate is added Material and flux cool down to adjust slag temperature, are 3. mixed using the strength such as stirring, the processing of slag are completed with this, then second Step makes slag-gold separation (i.e. slag is detached with iron), slag recycle, final " realize fused reduction iron-smelting, it is obtained by the reaction molten Slag is through processing, and the metallic iron aggregation that makes to be mingled with the pig iron and continue to be reduced is grown up and settled, and phosphorus component is enriched in rich phosphorus phase, logical Cross separation, obtain metallic iron or steel, rich phosphorus phase " patent purpose.The emphasis of process technology scheme is recycling phosphor resource, Yi Jitong It crosses a variety of methods and handles the slag after the separation of one gold medal of slag repeatedly, including being blown into oxidizing atmosphere makes slag iron oxide improve, so that Slag quality, at being grouped as, to make the value of low value slag improve, is deposited in a small amount of so-called of bottom closer to clinker Metallic iron or steel send pneumatic steelmaking.To the slag slag or blast furnace slag (hardly iron content) of this low value, take charging or Electrical heating temperature adjustment alkali tune degree, separation reprocessing utilize " two step method " processing method, and there is problems with:1, the technical staff Skill route fixes P (phosphorus), enrichment P with slag, and then it is direction to detach P recycling P in slag, by P2O5It controls, P is made not gone back Original enters molten iron, still with P2O5It is retained in slag, obtains 2CaOSiO2-3CaO·P2O5Rich phosphorus phase, cooling are precipitated and recycle P Element, it can only be that one kind being in oxygen blast that processing procedure entire in this way, which restores in a kind of Fe and controls the smelting situation that P is not restored, In the weakly reducing atmosphere for seeming oxidizing atmosphere under the property changed gas, therefore takes electrical heating to provide heat source, is stirred and comes by force Change treatment progress, to influence the reduction rate of iron, is in and faces a difficult choice among may restoring and do not restore between control iron and phosphorus Condition, the oxidisability or reducing atmosphere of processing are more difficult to control.2, it " is realized in mixing slag described in patent to realize The high efficiente callback of iron, silicon, calcium, phosphorus component " reaches the technique effect or purpose of " production molten iron, Silicon-rich calcium phase and rich phosphorus phase ", work Skill scheme takes " two step method " processing, the second last step " separation recycles slag-gold separation phase ", is not only forced using more Kind of sedimentation method, and it is prominent to the slag after separation, oxygen blast carries out oxidation processes again, improve iron oxide content in slag >= 2wt%, to improve it as the value of the clinker of standard quality, even if in this way, slag is as cement raw material, value is still So is not too high, the cost that time and effort consuming, slag are converted to cement raw material is higher, economically there is a problem of it is certain, although phosphorus Resource is valuable, and still, the rich phosphorus using the recycling of this technique is mutually also limited.Due to discontinuity processing, charging heating melting processing One stove, slag is clean after having detached, empty stove thermal loss, then adds batch of material heating melting, then handles a stove again, then cold But sedimentation separation, it is this to press the discontinuous process for producing mode of heat discontinuity, it is too cumbersome, be not easy to grasp, be not suitable for extensive big Bulk industrial organization of production especially takes electrical heating temperature raising mode, and power consumption is of high cost, it is expected that being excavated at a low price using this technique The slag of value or the inherent resource value of blast furnace slag, or the value of slag or blast furnace slag as clinker is promoted, meaning is not It is too big.
