Description
Technical Field
The invention belongs to metal smelting, and in particular relates to a bismuth removing device in pyrometallurgy of bismuth-containing antimonic ore.
Background
Bismuth is an important impurity element affecting the quality of antimony ingots and antimony oxide, but antimony and bismuth have close properties, and the pyrogenic separation is difficult, and along with the complicating of raw materials and the increase of high-bismuth raw materials, the research on the pyrogenic separation of antimony and bismuth is necessary.
The general standard for distinguishing high bismuth antimony from low bismuth antimony in the market is that the bismuth content is 100ppm, and the bismuth content is more than high bismuth antimony and less than low bismuth antimony. And the bismuth content in bismuth-containing antimonite is generally more than 500ppm.
At present, the pyrometallurgy of antimony mainly comprises two processes, namely, the volatilization smelting of a blast furnace, wherein most of bismuth in the process enters into oxygen powder of the blast furnace along with the volatilization of the antimony, and if the antimony is not treated, the bismuth enters into a second process reverberatory furnace for reduction refining, so that high bismuth antimony can be directly produced. A blowing process is generally added between the two processes. The process of volatilizing and blowing is to utilize the difference of the antimony and bismuth densities in a reverberatory furnace, wherein the antimony density is lighter than that of bismuth, the reverberatory furnace is arranged at the upper layer, air or oxygen is introduced into a smelting furnace to ensure that the antimony volatilizes and the bismuth does not volatilize,bismuth and antimony both in liquid form can react with oxygen to produce metal oxides (principally Bi 2 O 3 、Sb 2 O 3 Etc.), and is discharged through a chimney along with the flue gas, and finally bismuth is discharged into the furnace in the form of high bismuth-antimony alloy.
In the blowing process, the air pipe is fixed on the smelting furnace, the blowing angle and the position of the air pipe are not easy to control, so that the air pipe is in an air supply mode of blowing from outside to the middle, the thickness of antimony on the upper layer is very easy to be thin at the periphery, but the thickness of the antimony on the middle is thick, as shown in the attached drawing 1 of the specification, in the actual blowing process, bismuth necessarily exists, and when bismuth is not completely volatilized, bismuth at the position of the outer side close to the air pipe is volatilized, bismuth oxide necessarily exists in blown oxide, and finally the bismuth content of the produced antimony oxide is still very high, so that low bismuth and antimony cannot be obtained.
Chinese patent CN204022918U discloses an antimony powder converting furnace, specifically, a refractory wall and a blowing pipe with multiple air outlets are adopted, the air outlets are flat, the blowing pipe with multiple flat air outlets can prevent bending caused by high temperature during use, and the purity of the product is improved, but the removal of volatilized bismuth cannot be solved.
Chinese patent CN111057872A discloses a bismuth removing method in the refining process of an antimony smelting reverberatory furnace, specifically, an alkali metal compound is used as a bismuth removing agent, bismuth is removed after a blast stirring reaction according to a configured amount, a large amount of reagent is required to be consumed in the bismuth removing method by adopting a chemical reagent, the cost is high, only the bismuth in the reverberatory furnace can be removed, and the bismuth which has volatilized does not act.
Therefore, in the production process, not only the blowing direction and the blowing quantity of the liquid antimony are required to be controlled, but also the volatilized bismuth is required to be controlled, so that the really low bismuth antimony can be obtained; especially for volatilized bismuth, since it is not known when antimony has volatilized during blowing, bismuth begins to volatilize, so controlling the content of volatilized bismuth is important; in the case of oxides (Bi 2 O 3 、Sb 2 O 3 ) All are discharged in a gaseous state through a chimney, and oxide (Bi) can be obtained by cooling in the chimney 2 O 3 、Sb 2 O 3 ) Condensing into solid powder, wherein Bi 2 O 3 The melting point of Sb is 825 DEG C 2 O 3 The melting point of (2) is 655 ℃, so that Bi can be cooled to the temperature of 655-825 ℃ in the chimney in the condensation process 2 O 3 The smoke temperature in the chimney can be stirred along with the change of the outside, so that the temperature in the chimney is not easy to control, such as: after passing through the temperature-reducing region, if the temperature does not drop below 825 ℃ or only fluctuates around the temperature, the flue gas is practically reserved for Bi 2 O 3 The time and space for condensation are too little, and there is little way to give bismuth to condensate out; in addition, the pipe diameter of a common chimney is large, even if the chimney is divided into different small pipelines for discharging smoke, the temperature in the chimney can not realize integral cooling when cooling, so that the temperature difference of the chimney in a cooling area is large, the condensation effect is poor, and bismuth is not removed cleanly; on the other hand, the temperature at the temperature reduction part is very low, and some of the temperature reduction parts can be even directly lower than 600 ℃, so that bismuth cannot be removed, antimony can be condensed, and the yield of antimony in the final condensed product is very low, so that a device capable of removing bismuth from volatilized bismuth-antimony ore to produce low bismuth-antimony is needed.
