Description
The present invention relates to a kind of novel method of antimony regulus, specifically, is the method for bubble slag, alkaline residue being smelted star metal directly into reverberatory furnace.
Antimony regulus is the principle by redox reaction, and antimony ore is added coke, and burning is oxidized into antimonous oxide through blast furnace (or stoving oven), antimonous oxide is added charcoal again and enters reverberatory furnace and be reduced to antimony.Because the ratio of antimony is great, sinks to furnace bottom, and floating on the whole slag pulls out just to cry and steeps slag.In addition, the antimony that sinks to furnace bottom must add soda ash to remove impurity such as arsenic owing to contain harmful elements such as arsenic, selenium, iron, just can become star metal, and floating on the whole slag pulls out and just is alkaline residue.Alkaline residue generally contains the antimony amount about 30 degree, and the bubble slag generally contains the antimony amount about 35 degree.
Stibiated recovery in present this bubble slag, the alkaline residue, generally be to adopt to produce by indigenous method, be about to steep slag, alkaline residue and add after charcoal stirs, add the jar made from refractory mortar, one jar of canned kiln roasting that buries is after 24 hours then, make antimony sink to the jar bottom, one jar of jar takes out to hammer into shape and rots again, and the antimony regulus that sinks to the jar bottom is taken out, and is jar antimony, just can enter reverberatory furnace training of vital essence antimony at last, and in reverberatory furnace, also need add alkaline purification during training of vital essence antimony.This antimony regulus method is refined one ton of natron slag and need be consumed 1 ton of coal, 1.5 tons of refractory mortars, and on 22 of work work days, so the waste of antimony is big, the rate of recovery is low.Production cost height, labour intensity are also big, and the environmental pollution of open-air roasting refining jar antimony is quite serious, to the people, to around crops harm very big.Though now have the natron slag is gone into the conventional approach that reverberatory furnace reclaims star metal, the direct yield of its antimony generally has only about 60%, and is also uneconomical so the rate of recovery of antimony is extremely low, more can not reach the required ideal requirement of people.
The objective of the invention is provides a kind of novel method that will steep slag, alkaline residue directly into reverberatory furnace training of vital essence antimony for overcoming above-mentioned shortcoming.It both had been adapted to steep slag mixes with alkaline residue directly into reverberatory furnace training of vital essence antimony, and also be adapted to alkaline residue and go into reverberatory furnace training of vital essence antimony separately, and rate of recovery height, production cost is low, has the effect of coal saving height, can make production and application units all have tangible economic benefit.
Refinement of antimony by directly feeding natron residue into air furnace method proposed by the invention, its concrete grammar is: after at first former parison slag, alkaline residue are dewatered (oven dry), broken, press proportion ingredient then, and adding reductive agent (charcoal) 3% to 8% stirs, enter reverberatory furnace again and smelt star metal, carry out finishing and packing at last.Its technological process of production is:
Raw material preparation (bubble slag, alkaline residue) → dehydration (oven dry) → fragmentation → batching →
Smelt → go out star metal → finishing and packing.
Below the present invention is done to be described in detail further.
1. raw material is prepared: employed former parison slag, alkaline residue must be anticipated, and remove out some impurity and suitable of the present invention required.
2. dehydration: be that bubble slag, alkaline residue after handling are dewatered respectively, dehydration be adopt oven dry or natural dry all can, the water content in its bubble slag, the alkaline residue can not surpass 5%.
3. broken: the bubble slag after will dewatering, alkaline residue carry out fragmentation respectively in crusher, its broken granularity must be controlled at 1.5cm
3Below.
4. prepare burden: be the starting material that fragmentation is good, the used amount of slag and alkaline residue of promptly steeping is: the bubble slag is 30% to 50%, and alkaline residue is 50% to 70%.
5. stir: be that the natron slag that will prepare in proportion stirs in stirrer, add reductive agent (coal) 3～8% when stirring, the time of stirring is 10 to 15 minutes, and it adds the reductive agent granularity must be controlled at 1cm
3Below.
6. smelt: the natron slag that stirs is directly entered reverberatory furnace smelt, its natron slag is all melted, remain unchanged, after the fusing, if float over antimony waste residue waterborne also twice more than (being the antimony content in the waste residue), by first and second drum water, reduce to twice always below, be that antimony content in the waste residue must be controlled at below 2%, waste residue is all removed.
7. go out star metal: in order to remove the impurity in the antimony water, when going out star metal, must add soda ash 15% to 20%, to improve the purity of star metal.
8. finishing and packing: will smelt the star metal that from reverberatory furnace, be that available tr is packed and dispatched from the factory after coming out of the stove.
The novel method of above-mentioned refinement of antimony by directly feeding natron residue into air furnace, if under the situation of not steeping slag, present method can be smelted alkaline residue separately.
Owing to adopted technique scheme, the present invention compared with prior art has following advantage:
The present invention it solved and existing produced by indigenous method that to smelt the environmental pollution of jar antimony quite serious, the production cost height, labour intensity is big, the problem that the rate of recovery is low;
2. the present invention has also overcome existing traditional method directly into reverberatory furnace recovery star metal, the shortcoming that the rate of recovery is extremely low;
3. the present invention compares with existing smelting process, antimony content also has 8～16% in the waste residue that its existing method is produced, the star metal direct yield has only about 60%, and in the inventive method waste residue antimony content below 2%, the star metal direct yield can reach more than 80%, so the existing method of the direct economy value ratio of bubble slag per ton, alkaline residue is high about 650 yuan;
The present invention it both be adapted to the natron slag and mixed directly into reverberatory furnace training of vital essence antimony, also can be adapted to alkaline residue and go into reverberatory furnace training of vital essence antimony separately, and production cost is low, rate of recovery height, remarkable in economical benefits.
