摘 要: 基于硫化鉛礦在閃速爐功能區(qū)冶煉過程的多相同時平衡原理，利用平衡摩爾量法分析和討論熔煉溫度、初始氧量和初始硫化鉛量對平衡后各凝聚態(tài)產(chǎn)出量的影響。結(jié)果表明：在較高溫度下，初始氧量的增加會使硫酸鉛的產(chǎn)量增加，而硫化鉛的產(chǎn)量降低；低氧量條件下不生成硫酸鉛而生成硫化鉛。考慮產(chǎn)物的后續(xù)碳還原處理，在冶煉過程中應選擇高氧氣輸入量以生成容易處理的硫酸鉛，而不是較難處理的硫化鉛。

Abstract:Based on the multiphase simultaneous equilibrium principle of lead sulfide minerals smelting process in the functional area of flash furnace, Moore balance method was used to investigate the effect of smelting temperature, initial oxygen content and initial lead sulfide content on the output of each condensed matter after reaching equilibrium. The results show that, under high temperature condition, the output of lead sulfate increases, while with the increase of initial of oxygen content, the output of lead sulfide decreases. In addition, lower oxygen input cann’t result in the generation of lead sulfate, but lead sulfide will emerge. Considering the subsequent treatment of the products, it is suggested that higher oxygen input should be chosen during the smelting process, in order to generate the tractable lead sulfate rather than unmanageable lead sulfide.
