Embodiment 1

[0011] 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

[0013] 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 nonferrous metal antimony smelting, and discloses a tin removing agent in the refining process of an antimony smelting reflecting furnace. A compound ofalkali metal is used as the tin removing agent, and the compound of the alkali metal can be independently used or several compounds are adopted to be mixed according to a certain proportion to prepare the tin removing agent for antimony refining. The invention further discloses application of the tin removing agent in the refining production process of the antimony smelting reflecting furnace. Through the technical scheme, impurity tin elements in antimony can be effectively removed, the economic benefits are obvious, and meanwhile, the tin removing agent has the important significance in expanding the application field of antimony products in the industry.

Description

technical field [0001] The invention relates to the technical field of antimony smelting of non-ferrous metals, in particular to a tin remover in the reverberatory furnace refining process of antimony smelting and its application. 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 pro...
