摘要/Abstract

摘要： 针对铜渣贫化过程碳排放问题，以橡胶籽油取代柴油作为铜渣贫化的还原剂，研究铜渣贫化过程中的热力学，分析橡胶籽油贫化铜渣机理。在不同温度和时间条件下进行喷吹橡胶籽油贫化实验，分析铜渣磁性铁含量和粘度的变化，用XRD和SEM对贫化后炉渣进行分析。结果表明，喷吹还原过程中主要还原剂是裂解产生的碳单质、H2和CO。贫化过程中磁性铁被橡胶籽油在高温下的裂解产物(H2, CO, C)还原成FeO，与渣中的SiO2结合生成铁橄榄石(Fe2SiO4)；随贫化温度升高，相同喷吹时间内铜渣的磁性铁含量和粘度逐渐降低，使渣中的Cu相互碰撞聚集，最终沉降到坩埚底部。随贫化进行铜渣中的铁橄榄石相增多，磁性铁相减少。在坩埚底部聚集的铜颗粒粒度由1 cm增至3 cm，铜回收率达86%。
