Example Embodiment

[0011] Example 1

[0012] The 18㎡ reverberatory furnace refining and chromium removal operation uses a certain alkali metal compound as a chromium removal agent. Before refining, the antimony liquid contains 0.04% chromium. The weight of the antimony liquid is estimated to be 50 tons. Add the prepared chromium removal agent 1.5 at 950℃~1000℃ Tons, the slag is discharged after 1 hour of blast stirring, and the antimony liquid contains 0.001% of chromium, which is better than the expected value, and the chromium removal effect is significant.

Example Embodiment

[0013] Example 2

[0014] 16㎡ reverberatory furnace refining chromium removal operation, using a certain alkali metal compound as a chromium removal agent. Before refining, the antimony liquid contains 0.03% chromium, and the weight of the antimony liquid is estimated to be 45 tons. Add the prepared chromium removal agent at 950℃~1000℃. Tons, the slag is discharged after 1 hour of blast agitation, and the antimony liquid contains 0.0006% of chromium, which is better than the expected value, and the chromium removal effect is significant.

Abstract

The invention relates to the technical field of non-ferrous metal antimony smelting, and discloses a chromium removal method in the production and refining process of an antimony smelting furnace. Thechromium removal method comprises the steps that an alkali metal compound is used as a chromium removal agent, the chromium content of the antimony liquid before refining is 0.03%-0.05%, the antimonyliquid weight is 45-50 tons, and at the temperature of 950-1,000 DEG C, 1.5-20 tons of a tin remover are prepared and added; after air blowing for 1 hour and stirring for 1 hour, slag is discharged,and the chromium content of the antimony liquid in a sampling test is 0.00001%-0.0006%; and after the reaction is completed, the produced chromium slag floats on the surface of the antimony liquid, and the chromium removal scum is discharged out of the furnace from an operation door. By using the technical scheme of the chromium removal method, the impurity chromium element in antimony can be effectively removed, the economic benefit is remarkable, and meanwhile, the method has important significance in expanding the application field of antimony products in the industry.
