摘要 本文研究了艾萨铜熔炼入炉精矿所含主要元素及成分的作用,结合生产实际,对比单一硫化矿配料模式、硫化矿加氧化矿联合配料模式对艾萨铜熔炼的影响,以寻求更符合、更利于艾萨铜熔炼的优化配料模式。结果表明,在硫化铜精矿中配入比例合适的氧化铜矿,可使原料的Fe、S、SiO_(2)含量更接近生产工艺需求,减少辅料的使用,可加快熔炼及吹炼环节的生产节奏,增加流程产量,提高工艺平衡匹配,减少冶炼过程中热能浪费,降低能耗。 In this paper,the functions of main elements and compositions of the concentrate fed for ISA copper smelting were studied;based on production practice,a comparison was made between two blending modes for their influence on ISA copper smelting,so as to find a more suitable and favorable blending mode for ISA copper smelting.The two modes are respectively as blending with sulfide ore only and blending with sulfide ore and oxide ore.The comparison results show that adding a proper proportion of copper oxide ore in copper sulfide concentrate can make the Fe,S and SiO_(2) content in the feed closer to the production process requirements and result in lower consumption of auxiliaries,increased smelting and converting efficiency,improved production capacity and process balance rate,reduced heat energy waste in smelting and reduced energy consumption.
