Embodiment 1

[0048] The method for producing crude antimony trioxide by smelting in the oxygen-enriched side-blown volatilization pool of this embodiment comprises the following steps:

[0049] (1) The antimony-containing materials, anthracite, iron ore, and lime are measured according to the mass ratio of 100:17:22:10 from each silo 1 through the corresponding metering belt 2, and then transported to the furnace by the transfer belt 3 The electronic belt scale 4 on the top and the electronic belt scale 4 measure the total weight of the furnace materials, and then put them into the oxygen-enriched side-blown volatilization melting pool melting furnace through the feeding port 5. The area of ​​the oxygen-enriching side-blowing volatilization melting pool melting furnace is 2.16m 2 (1.2×1.8m), the materials entering the furnace undergo melting, dissociation, desulfurization, oxidation, volatilization and slagging reactions in the furnace. During the melting and reaction process, 75% (V / V) ox...

Abstract

The invention discloses a method and a device for producing crude antimony trioxide by smelting of a rich oxygen side-blown volatile molten pool. The method comprises the following steps: by taking an antimonial material as a raw material, blind coal or coke or a natural gas or a coal gas and the like as supplement fuel, and iron ore and lime as fluxes, blowing oxygen-enriched air, entering a furnace to react after metering a charging material, so as to produce high-temperature smoke and melt; condensing and dedusting the high-temperature smoke, and then feeding the smoke to an acid making system to prepare an acid, wherein the condensed powder is a crude antimony trioxide product to feed to the next procedure to process; respectively discharging the high-temperature melt after settling and layering in a hearth; quenching the slag to be directly used as a waste slag, and returning a little of produced antimony matte and crude antimony; and feeding noble antimony to the next procedure to process and extract gold. The invention also comprises a device for producing crude antimony trioxide by smelting of a rich oxygen side-blown volatile molten pool. The device has the advantages of being strong in raw material adaptability, low in energy consumption, high in smoke SO2 concentration, high in direct recovery rate and recovery rate of antimony and noble metal, clean and environment-friendly to produce, low in production cost and the like, and the acid can be directly prepared.

Description

technical field [0001] The invention relates to a method and a device for producing crude antimony trioxide, in particular to a method and a device for producing crude antimony trioxide by smelting in an oxygen-enriched side-blown volatilization molten pool. Background technique [0002] Antimony metallurgy is divided into pyrometallurgy and wet method. At present, the pyrometallurgical process in the production of antimony metallurgy has an absolute advantage, reaching more than 95%; and the technological process of "antimony concentrate blast furnace volatilization smelting-coarse antimony trioxide reverberatory furnace reduction smelting" It is the basic process of most antimony smelters in my country at present. [0003] The antimony blast furnace volatilization smelting process has the advantages of strong raw material adaptability, large processing capacity, and easy mechanical operation, but the special operating conditions of "low material column, thin material layer,...
