Abstract
After material weighing, burdening and mixing, the material is smelted in reverberator, and then scorified by adding 3-8% of catalyst, which reacts with impurity for making slag to be separated from antimony, and finally after smoke and slag treatment, refining and casting to produce antimony ingot. This smelting process can reduce the antimony content in the slag to below 3% as well as reduce antimony smelting cost, shorten smelting period, and reduce environmental pollution.
Description
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.
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.
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 of adding 3～8% in the time of slag making, make catalyzer and other material in antimony regulus produce chemical reaction, promote slag antimony to separate, carry out clearly cigarette at last, locate slag, refining, ingot casting become antimony slab.
Accompanying drawing has been described embodiments of the invention.
As among the technological process of production figure and this above-mentioned smelting process from antimony raw material, metering, prepare burden, be stirred to into reverberatory furnace and smelt, and slag making, clear cigarette, locate slag, refining to ingot casting becomes antimony slab, all be to adopt existing manufacturing technique technology smelting process.It mainly adds 3～8 catalyzer in slag making exactly simultaneously.
Add catalyzer in present method when slag making, its catalyzer is made up of antimony sulfide, vitriolate of tartar and soda ash, is 100: 3: 10 in the ratio of forming.
The catalyzer that adds in slag making is to adopt artificial way directly to add.
This smelting process only needs the catalyzer in smelting slag making process adding 3～8%, just can impel slag antimony to separate, and slag antimony is controlled at below 3%, so method is simple especially.It does not exist the method for employing blast furnace or flotation to reclaim slag antimony more simultaneously, and it can become antimony slab with the primary smelting of antimony raw material, so ton antimony can reduce production costs 300～800 yuan, and reduce 2/3rds than former method, non-environmental-pollution tap to tap time.
Claims (2)
1. smelting process that reduces antimony content in slag comprises raw material metering, batching, stirring, reverberatory furnace smelting, slag making, clear cigarette, locates slag, refining, ingot casting become antimony slab, it is characterized in that adding in slag making 3～8% catalyzer.
2. according to the smelting process of the described reduction antimony content in slag of claim 1, it is characterized in that catalyzer is made up of antimony sulfide, vitriolate of tartar and soda ash, be 100: 3: 10 in the ratio of its composition.
