摘　　要：通过分析典型铅基固废的元素组成与物相组成,提出了原生铅精矿与铅基固废协同处理的工艺方案。通过工业化试验确定原生铅精矿与铅基固废协同处理过程中的比例,在配入铅膏9.47%、铅烟尘16.93%、浸出渣8.4%、铅玻璃0.93%时,生产系统可以实现自热,还原炉渣含铅小于2%。基于此技术投产的大型氧气底吹熔炼-底吹还原-还原渣烟化挥发生产系统,年处理含铅物料75万t,铅基固废最大配入量可达到35.73%。By analyzing the elemental composition and phase composition of typical lead-based solid waste,a collaborative treatment scheme of primary lead concentrate and lead-based solid waste was proposed.The proportion of primary lead concentrate and lead-based solid waste in the collaborative treatment process was determined by the industrial experiment.When the lead paste 9.47%,the lead dust 16.93%,the leaching slag 8.4%and the lead glass 0.93%were added,the production system could realize self-heating and the lead content in the reducing slag was less than 2%.Based on this technology,the large-scale oxygen bottom blow melting,bottom blow reduction and fume volatilization production system of reduction slag can process 750000 tons of lead-containing materials annually,and the maximum amount of lead-based solid waste can reach 35.73%.
