Method of adopting oxygen-enriched vortex bath smelting furnace for treatment of jamesonite

Abstract

The invention discloses a method of adopting an oxygen-enriched vortex bath smelting furnace for treatment of jamesonite. The oxygen-enriched vortex bath smelting furnace comprises a furnace body and a plurality of spray guns, the furnace body with a feeding port, a discharging port, a smoke outlet and a slag outlet is provided with a furnace cavity with a circular cross section, and the side wall of the furnace body is provided with a plurality of spray gun insertion holes distributed at intervals along the periphery of the furnace body. The spray guns are inserted into the spray gun insertion holes and deviates in the same direction from the circle center of the circular cross section of the furnace cavity. The method includes the steps: feeding jamesonite into the furnace cavity through the feeding port; spraying oxygen-enriched air into the furnace cavity by the aid of the furnace cavity, generating antimonial lead slag, smoke and lead-antimony alloy by reaction of the jamesonite in the furnace cavity; discharging antimonial lead slag from the slag outlet, exhausting the smoke from the smoke outlet and discharging the lead-antimony from the discharging port. The method for adopting the oxygen-enriched vortex bath smelting furnace for treatment of jamesonite has the advantages of low energy consumption and excellent smelting effects.

Description

technical field [0001] The invention relates to a non-ferrous metallurgy method, in particular to a method for treating brittle pyro-lead-antimony ore with an oxygen-enriched vortex molten pool melting furnace. Background technique [0002] A relatively common problem in molten pool smelting metallurgical furnaces in the related art is that the materials fed into the furnace from the feed port tend to float on the surface of the melt, and cannot fully participate in the molten pool reaction, affecting production efficiency, and sometimes even cannot produce normally. For example, in the side-blowing smelting technology in the related art, the side-blowing lance blows toward the center of the furnace body, and the blowing produces a certain stirring effect on the melt in the furnace, but the materials added at the top tend to float on the surface of the melt, making it difficult to enter the melt. body fully participates in the reaction. Although the top-blowing smelting tec...

[0002] A relatively common problem in molten pool smelting metallurgical furnaces in the related art is that the materials fed into the furnace from the feeding port tend to float on the surface of the melt, and cannot fully participate in the molten pool reaction, which affects production efficiency and sometimes even fails to produce normally.

For example, in the side-blowing smelting technology in the related art, the side-blowing lance blows toward the center of the furnace body, and the blowing produces a certain stirring effect on the melt in the furnace, but the materials added at the top tend to float on the surface of the melt, making it difficult to enter the melt. Participate fully in the response

Although the top-blowing smelting technology in the related art can stir the molten pool, the working principle of the top-blowing lance makes the melt roll up and down too violently in the furnace. In order to avoid splashing, the top-blowing furnace must increase the height of the furnace body, which leads to the construction of the furnace body. Difficult to increase the cost of furnace body and spray gun
