Abstract
The present invention relates to a method and a device for preparing stibium white from jamesonite, which belongs to the metallurgy field. The present invention is characterized in that after arsenic is oxidized and removed in advance, the stibium white is prepared from the jamesonite under the conditions that an alloy fusant is controlled below 700 DEG C, and a furnace chamber space is controlled to be 150 to 450 DEG C by a special designed oxidizing furnace. The technology has the advantages of short process and high metal recovery rate. The Pb recovery rate and the Ag recovery rate are both larger than 93%, the Sb recovery rate is larger than 80% and is enhanced by 10 to 15% as compared with that of traditional technology. Equipment investment is reduced by more than 60% as compared with that of the traditional technology, and thus, the present invention is easy to realize in industry.
Description
The invention belongs to field of metallurgy, particularly stibium fire is smelted deleading and arsenic, extracts stibium trioxide.
When adopting pyrorefining, the difficulty or ease that impurity is removed in the antimony mainly are to reach each other the difference of chemical property by these impurity and metallic antimony bonded state to decide.The chemical property of impurity arsenic and antimony is very close, and difficulty is removed, and lead is the most difficult removing then.
Traditional fire refining deleading and arsenic, the technical process of producing stibium trioxide is:
1. at first with mineral aggregate desulfurization in fluidizing furnace;
2. sintering briquetting then;
3. again through the blast furnace roasting reduction, the thick alloy of output;
4. then thick alloy is entered the reverberatory furnace blowing, make plumbous antimony initial gross separation; At this moment, most of antimony voloxidation is reclaimed, and lead then becomes lead bullion;
5. again needle antimony is added the reduction of refining reverberatory furnace;
6. add Na again
2CO
3Impurity such as As are removed in refining, obtain low arsenic lead antimony alloy;
7. add and obtain No. two star metals after phosphoric acid salt removes Pb;
8. once more to the oxygen blast of tertiary air formula oxidized still,, produce qualified stibium trioxide with No. two antimony.
This technical process is long, and especially the weak effect of separation of lead, arsenic because antimony metal needs secondary oxidation can make qualified stibium trioxide, causes metal recovery rate low, stibium trioxide production cost height.
The object of the present invention is to provide technical process short, and the high method and apparatus of metal recovery rate.
The present invention with whole process with preparing stibic white with jamesonite, shortened to for three steps for achieving the above object:
The first step, with common reverberatory furnace with raw ore, soda ash, go back raw coal and mix, with the blowing process direct melting that feeds intake, obtain thick alloy;
Second step, adopt conventional reverberatory furnace basic refining earlier, make arsenic change into the sodium arseniate scum silica frost and remove;
The 3rd step, adopt custom-designed crucible type oxidized still, control suitable condition, the blowing oxidation, the metallic antimony voloxidation, lead is enrichment in residual melt then, draws from process, thus and thus, makes lead thoroughly separate the highly purified stibium trioxide of output with antimony.
Special arrangement of the present invention is characterized in that described body of heater 11 is connected with heat supply chamber 1, and melt is by indirect heating.One air deflector 8 that has a guide duct 3 is installed in this body of heater, and its top is gas tank 4, and its underpart fills alloy melt; Air deflector 8 is equipped with induced exhaust 5 and passes gas tank 4 and communicate with dust chamber 6 through citation damper; Guide duct 3 on the air deflector 8 is communicated with gas tank 4 and melt liquid upper surface.
Technical process of the present invention is simple, facility investment is little, product recovery rate is high, and production cost is low, remarkable in economical benefits, and industrial being easy to realize, is applicable to that the lead antimony alloy that any ratio, any method obtain produces stibium trioxide.
Be further described below in conjunction with accompanying drawing.

Accompanying drawing has been described the crucible type oxidized still, and it has a crucible shape body of heater 11, and an air deflector 8 that has a guide duct 3 is installed in this body of heater, and its top is gas tank 4, and its underpart fills alloy melt; Air deflector 8 is equipped with induced exhaust 5 and passes gas tank 4 and communicate with dust chamber 6 through citation damper; Guide duct 3 on the air deflector 8 is communicated with gas tank 4 and melt liquid upper surface; Body of heater 11 has melt intake 2 and communicates with the primary heater unit 13 that fills low arsenic alloy 14, and body of heater 11 has slag-drip opening 9.
Accompanying drawing has been described process implementing process of the present invention, with the low arsenic alloy 14 of fused, introduces in the custom-designed crucible type oxidized still through feeder sleeve 2, and this alloy contains Pb2～92%, and the Sb stable content is between 98～8%; Crucible type oxidation body of heater 11 is connected by indirect heating with heat supply chamber 1, makes the alloy melt temperature-stable below 700 ℃; Control blast channel 7 evenly blasts 900～3000Pa air or oxygen by the alloy surface in stove of the guide duct 3 on furnace roof gas tank 4 and the air deflector 8, makes alloy be in relative static conditions; Adjust air flow rate and pressure, the furnace cavity temperature is remained between 150～450 ℃; Constantly remove the alloy surface coverture from slag-drip opening 9, to keep alloy surface bright and clean; When Sb content less than 8% the time, stop oxygen blast, from drain hole 12 beginning blowings, promptly get and hang down stibium crude lead, and passing on potroom, to extract electricity plumbous, behind the anode sludge melting, circulation enters the oxidized still oxygen blast; Meanwhile, the citation damper that be equipped with at control induced exhaust 5 places is introduced bagroom 6 internal furnace mixed gass with controlled underbalance, obtains meeting the antimonous oxide of national standard, i.e. stibium trioxide through collection.
The present invention compares with prior art and has the following advantages:
1. technical process is short, and operation is easily gone, and can realize automatic or semi-automatic;
2. metal recovery rate height, Pb, Ag metal yield all＞93%, Sb metal recovery rate＞80% improves 10～15% than the traditional technology Sb rate of recovery; Pb, g metal yield improve＞5%;
3. the finished product are highly processed goods, and finished product appreciate 17% than No. two antimony of tradition, and tooling cost reduces by 10～15%;
4. smelting process SO
2Discharging reduces more than 50%, and directly smelting process reduces arsenic dirt, and the workshop labor condition is improved;
5. this traditional technology of facility investment reduces more than 60%, and industrial being easy to realized;
6. end product quality is being better than traditional technology aspect regular crystal ratio, the particle uniformity coefficient;
7. the present invention is applicable to leaded antimony sulfide ore or the antimony oxide ore that can not produce No. two antimony with two steps of conventional method.
