Embodiment 1

[0012] 18㎡ reverberatory furnace refining tin removal operation, using an alkali metal compound as a tin removal agent, the antimony liquid contains 0.05% tin before refining, the weight of the antimony liquid is estimated to be 50 tons, and the prepared tin removal agent 2 is added at 950 ° C ~ 1000 ° C The slag was produced after stirring for 1 hour. The antimony solution contained 0.001% tin, which was better than the expected value, and the tin removal effect was remarkable.

Embodiment 2

[0014] 16㎡ reverberatory furnace refining tin removal operation, using an alkali metal compound as a tin removal agent, the antimony liquid contains 0.03% tin before refining, the weight of the antimony liquid is estimated to be 45 tons, and the prepared tin removal agent 1.5 is added at 950 ° C ~ 1000 ° C The slag was produced after stirring for 1 hour, and the antimony solution contained 0.0006% tin, which was better than the expected value, and the tin removal effect was remarkable.

Abstract

The invention relates to the technical field of smelting of the non-ferrous metal--antimony, and discloses a tin removing method used in reverberatory refining process of antimony smelting. Accordingto the invention, a certain alkali metal compound is used as a tin removing agent; the tin content of antimony liquid before refining is 0.03%-0.05%, and the weight of the antimony liquid is 45-50 tons; 1.5-2 tons of the prepared tin removing agent is added at 950-1000 DEG C, slag is discharged after blast stirring is conducted for one hour, sampling is conducted, and the tin content of the antimony liquid is 0.0001%-0.0006% according to test results; and slag without tin produced after a complete reaction can float on the surface of the antimony liquid, and dross without tin is pulled out ofa furnace from an operation door. With such a technical scheme, impurity tin in antimony can be effectively removed, remarkable economic benefits are obtained, and meanwhile, the tin removing method is of important significance in expanding the application field of antimony products in industrial engineering.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal antimony smelting, in particular to a method for removing tin in the reverberatory furnace refining process of antimony smelting. Background technique [0002] During the smelting process of non-ferrous metal antimony, impurity tin affects the quality of antimony products and restricts the application of antimony products in industry, but so far there is no effective method for removing tin in the production and refining process of reverberatory furnaces for antimony smelting. [0003] In the research and practice process of this method, the inventor of the present invention finds: comprise the compound of alkali metal; Use the compound of described alkali metal alone or mix with several kinds in a certain proportion and prepare antimony refining tin removal agent, It has a very good tin removal effect in the reverberatory furnace refining process of antimony smelting and production, and...
