Description
Technical field
The invention belongs to the technical field of tin is reclaimed in lead bullion, and in particular to a kind of method that waste residue containing slicker solder reclaims tin.
Background technology
Tin has a wide range of applications in many fields, particularly electronics, material industry, and the Tin Resources reserves of China are located at
The first in the world, tin and antimony, tungsten, rare earth simultaneously turn into the four major strategies resource of China, and current most of lead smelting enterprises are all with tin
The form of slag is triumphant cruel, is blown from reverberatory furnace and reaches the purpose for reclaiming tin, and its tin recovery technology production procedure is lead bullion in anode pot
Tin 40%, which enters, during founding removes copper dross slag, and 60% enters lead bullion positive plate；During lead wet method point solution in lead bullion positive plate 40% tin with lead
One starting point is parsed, 60% enters lead electrolysis anode sludge；It is enriched in into the tin for separating out lead in pyro-refining in lead bullion slag, essence
The reflected stove blowing of lead skim obtains scruff；Lead anode slurry 80% tin in reverberatory smelting, which enters, blows slag, and 10% enters precious metals containing lead,
10% enters slag, and because this stanniferous slag contains, noble metal is higher directly to open a way, and stanniferous slag is melted down into melting production repeatedly
The tin gone out blows that the separation of slag metal is poor, and the metallic lead taken away with slag, bismuth, silver are more, using antimony as 13% left side for very, accounting for total antimony amount that feeds intake
The right side, improves the secondary smelting cost of reprocessing, and the stanniferous amount of output scruff is low（10-20%）, price it is low, also have part lead smelting
Refining enterprise is blown using reverberatory furnace to be directly enriched with tin from lead bullion and obtains tin and blow slag, by tin blow slag repeatedly reduction melting obtain with
The suitable tin alloy of thick solder compositions, Zai Song tin factory's electrolysis process or other PROCESS FOR TREATMENTs are reclaimed, and this way of recycling is still deposited
Big, the defect such as secondary smelting cost height reprocessed in production process in processing high energy consumption and environmental pollution, these methods are all
It is that different phase is handled containing scruff in being smelted for lead, to reach the purpose of recovery tin, this processing means are present in
Tin is dispersed into different centres or final products, adds tin reclaimer, and tin can also influence the matter of lead as accessory substance
Amount.
The content of the invention
The purpose of the present invention is that there is provided a kind of method that waste residue containing slicker solder reclaims tin the problem of being directed to existing.
The present invention is achieved by the following technical solutions：A kind of method that waste residue containing slicker solder reclaims tin, including it is following interior
Hold：

The adding proportion of orange oil is 1-2% in the oxygen entered, and oxidation stops charging after terminating, only add anthracite and quartz, reduction
Phases-time is 80-90min；
C. in the slagging stage, slag tap is opened, the slagging time is about 30min, obtains thick tin；
（3）Thick tin from thick refining workshop is melted in product pot, condensation method removes iron, plus sulphur copper removal, vacuum drying oven vacuum distillation
Except lead, antimony, bismuth alloy, flowed out after tin is enriched by tin-tube, obtain refined tin；
（4）By from vacuum drying oven refined tin add fireless cooker melting after, add equivalent to refined tin weight 0.022% sodium hydroxide,
0.008% zinc hydroxide and 0.014% rosin, whipping temp are 460-475 DEG C, stir 45-55min, obtain crystallizing tin, press
Tin slab, which is made, in conventional method can be put in storage sale.
As further improvement of these options, the preparation method of the vinegar wood chip is：By weedtree wood chip with
Vinegar liquid is by weight 2:3 mixing, are sealing thermal insulation under conditions of 55-65 DEG C in temperature, after the completion of drain away the water, drying is to aqueous
Measure as 12-18%；Adsorbent is that lithium base oxygen is dedicated molecular sieve used.
As further improvement of these options, the active ingredient of the orange oil is 95%.
As further improvement of these options, the orange oil is heated to 65-70 DEG C, with oxygen after being atomized with atomizer
Gas is mixed.
As further improvement of these options, the oxidizing semlting stage, bath temperature control is 870 DEG C, oxygen-enriched
The adding proportion of air oxygen concentration control orange oil in 80%, the oxygen being passed through is 6%, stove internalization while stirring to clinker
Learn reaction to carry out, the time is 125min.
As further improvement of these options, the reduction melting stage, bath temperature is controlled at 1250 DEG C, oxygen-enriched
The adding proportion of air oxygen concentration control orange oil in 46%, the oxygen being passed through is 1.4%, and oxidation stops charging after terminating,
Anthracite and quartz are only added, the reduction phase time is 85min.
In smelting process, tin, lead, antimony, copper, silver, the bismuth rate of recovery are 97%, 97%, 97%, 97%, 90%, 95%, in clinker
The materials such as silica, calcium oxide, aluminium carbonate are mainly contained, 75% iron enters clinker.
The present invention has advantages below compared with prior art：Carried out in the present invention by the condition to raw material, smelting process
Regulation and control, can effectively control the energy consumption in the iron-holder in thick tin, reduction fusion process, tin is reduced to greatest extent
Out, realize reduces refined tin consumption again while comprehensive utilization, except tin efficiency reaches that stanniferous amount is less than in more than 99%, lead
0.0001%, effective utilization of product resource is realized, lead, tin separation phase energy consumption are smaller, remarkable in economical benefits.
