Abstract
The fire process for refining Sb while effectively removing Pb features that after atomized by nitrogen, liquid lead remover containing oxacid of phosphorus and sulfuric acid is directly sprayed into molten Sb. Its advantages are high refining speed, lead-removing effect and direct yield.
Description
The present invention relates to a kind of method for removing lead and deleading agent thereof that needle antimony is carried out pyrorefining.
In the pyrorefining antimony process, its associated metallic lead major part enters in the needle antimony, and the finished product star metal or stibium trioxide have certain requirement to the content of lead, star metal requires lead tolerance 0.1-0.2%, stibium trioxide requires lead tolerance less than 0.1%, to reach such standard undoubtedly, must carry out the refining lead-removing operation needle antimony.Existing method for removing lead has vacuum distillation method, chlorination process and liquation process.The vacuum distillation method deleading is effective, but the equipment complexity; The chlorination process direct yield is low, and environmental pollution is serious; Liquation process throughput is little, only the production of suitable high purity antimony.
Weak points such as 94113150.5 number patent application has proposed " a kind of ammonium salt deleading method that is used for fire refining of antimony ", its ammonium salt deleading agent prepares easily, application apparatus is simple, deleading is effective, but exists smog big, and refining time is long.
The purpose of this invention is to provide a kind of efficient deleading method and liquid deleading agent thereof that is used for fire refining of antimony, accomplish to improve refining speed, deleading effect and direct yield.
The present invention seeks to realize like this: at first oxygen acid, sulfuric acid and the stablizer with phosphorus is mixed with liquid deleading agent, directly spray in the high temperature antimony melt after then liquid deleading agent being atomized with nitrogen, plumbous in deleading agent and the melt fully contact fast, and generation is taken off lead more completely and is reacted.
The preparation method of liquid deleading agent is as follows: earlier that oxygen acid, the sulfuric acid of phosphorus is mixed by a certain percentage, carry out processed, and add 15% stablizer then and carry out stabilization treatment, obtain liquid finished product.Stablizer is any one in ammonium chloride, bicarbonate of ammonia, Vanadium Pentoxide in FLAKES, the phosphamide.The oxygen acid of phosphorus includes ortho-phosphoric acid, metaphosphoric acid, tetra-sodium, peroxophosphoric acid, polymer phosphate.
The weight percent of liquid each component of deleading agent is the oxygen acid 80-0% of phosphorus, sulfuric acid 0-85%, stablizer 15%.
Fig. 1 is a reverberatory furnace deleading equipment connection diagram.
Fig. 2 is an electric furnace deleading equipment connection diagram.
Be described in detail algorithm of the present invention and method below in conjunction with drawings and Examples.
Embodiment one, the efficient deleading method of reverberatory furnace.
At first the needle antimony of adding leaded 0.82% in reverberatory furnace 5 is 12 tons, in storage tank 2, add 250 kilograms of liquid deleading agents, start nitrogen machine 1 and volume pump 3 then, respectively nitrogen and liquid deleading agent are sent into nozzle 4, the deleading agent after nitrogen and the atomizing will directly be sprayed in the antimony melt by nozzle 4.Nitrogen plays the atomizing deleading agent and stirs antimony melt dual function.Temperature of reaction is 700-1100 ℃, and the time is 20 minutes, and the lead compound scum silica frost that generates in the reaction process should constantly claw, and can obtain lead tolerance at last and be 0.12% star metal more than 11.5 tons.
Embodiment two, electric furnace highly effective deleading method.
As shown in Figure 2, nitrogengas cylinder 6 is communicated with vial 8 tops by tensimeter 7, and vial 8 bottoms are communicated with crucible 9 middle parts, and crucible 9 is contained in the electric furnace 10.
At first in crucible 9, add leaded 0.52% needle antimony 3000 grams, in vial, add liquid deleading agent 40 grams, be warmed to 850-900 ℃ then, open and to get more than leaded 0.069% star metal 2900 grams.
Compared with the prior art, characteristics of the present invention are the atomizings of deleading agent process, Deleading agent after the atomizing can be sent out with the lead in the antimony melt under the stirring of nitrogen Give birth to i.e. fast again fully reaction, so refining speed is fast, deleading is effective, The direct yield height.
