Abstract
The present invention relates to a smelting process for lowering antimony content in slag. Firstly, raw materials are conveyed into a reflecting furnace to be smelted after metered, mixed and agitated. Then, slag is formed, and 3 to 8% of catalysts are added when forming the slag so that the catalysts generates chemical reaction with other substances in antimony smelting so as to promote the separation of the slag and antimony. Finally, smoke removal, slag removal, refinement and ingot casting are carried out to form an antimony ingot. In the smelting process, only catalysts are needed to be added to prompt the separation of the slag and the antimony, and the antimony slag is controlled to be below 3%. Thus, the process is simple, the production cost of the antimony per ton can be reduced by 300 to 800 yuan, smelting time is reduced by 2/3 than that of the existing process, and the present invention does not have environment pollution.
Description
Technical field:
The present invention relates to a kind of smelting process that reduces antimony content in slag, specifically, is to adopt catalyzer that antimony in the slag is controlled at below 3%, improves a kind of smelting process of the antimony metal rate of recovery.
Background technology:
During the pyrometallurgical smelting antimony slab, adopt oxide compound antimony raw material to join soda ash, coal, salt etc. usually and carry out antimony regulus, because of the antimony content difference of antimony raw material, length difference of clear cigarette time of melt contains the antimony amount and is generally 15～25% present method in the slag when antimony regulus.And the normal employing of this slag antimony advances the method for blast furnace or flotation again and reclaims, but these two kinds of methods still do not reach necessary requirement, and the antimony metal rate of recovery is low, and the production cost that causes is also high, and environmental pollution is big.It is according to investigations, domestic that also do not have can be with the smelting process below 3% in the antimony control in the slag.
Summary of the invention:
The purpose of this invention is to provide a kind of smelting process that reduces antimony content in slag, it can become antimony slab with the primary smelting of any antimony raw material, improves the antimony metal rate of recovery effectively, and antimony content in slag is controlled at below 3%.
Foreign material such as a spot of iron, copper all being arranged in the oxide compound of any antimony raw material, and utilize the sulphur in the antimony sulfide mineral, make other material in antimony regulus produce chemical reaction, promote slag antimony to separate, is the approach that improves metallurgical effect.
The smelting process that reduces antimony content in slag is: at first be to go into reverberatory furnace after raw material is measured, prepares burden, stirs to smelt, carry out slag making then, the catalyzer that adds institute's melting raw material weight 3～8% in the time of slag making, described catalyzer is made up of antimony sulfide, vitriolate of tartar and soda ash, it forms weight ratio is 100: 3: 10, make catalyzer and other material in antimony regulus produce chemical reaction, promote slag antimony to separate, carry out clearly cigarette at last, remove slag, refining, ingot casting become antimony slab.
Owing to adopt technique scheme, the present invention has well realized goal of the invention, its method is simple, it is convenient to implement, it does not exist the method for employing blast furnace or flotation to reclaim antimony contained in the slag more simultaneously, and it can become antimony slab with the raw material primary smelting, so ton antimony can reduce production costs 300～800 yuan, and reduce 2/3rds than former method tap to tap time, non-environmental-pollution.
Description of drawings:
Accompanying drawing is technological process of production figure of the present invention.
Embodiment:
Below by embodiment the present invention is further described.
As among the technological process of production figure from antimony raw material, metering, prepare burden, be stirred to into reverberatory furnace and smelt, and slag making, clear cigarette, remove slag, refining to ingot casting becomes antimony slab, all adopts existing manufacturing technique technology smelting process.Its characteristics are exactly that raw material according to different mass, performance adds 3～8% catalyzer in the raw material weight ratio of melting in slag making, described catalyzer is made up of antimony sulfide, vitriolate of tartar and soda ash, it forms weight ratio is 100: 3: 10, produce chemical reaction with other material such as the contained sulphur of catalyzer, the same copper of sodium, iron, silicon, precipitate and separate antimony, the control antimony content in slag.
When slag making, add catalyzer in present method, adopt artificial way directly to add.
Claims (1)
1, a kind of smelting process that reduces antimony content in slag, comprise raw material metering, batching, stirring, reverberatory furnace smelting, slag making, clear cigarette, remove slag, refining, ingot casting become antimony slab, it is characterized in that in slag making, adding the catalyzer of institute's melting raw material weight 3～8%, described catalyzer is made up of antimony sulfide, vitriolate of tartar and soda ash, and it forms weight ratio is 100: 3: 10.
