摘　　要：采用XRF、XRD、SEM-EDS、TG-DSC、Mossbauer以及金相显微镜对炉渣的化学组成、结构及形貌特征进行了详细研究。金相显微分析以及SEM-EDS表明了炉渣中各主要渣相为铁橄榄石相、磁铁矿相、冰铜相及无定型玻璃体相。通过XRD以及Mossauber检测发现渣中铁主要存在于铁橄榄石中,仅含有少量的磁性氧化铁。对炉渣的可选性分析认为,通过细磨可浮选回收炉渣中的铜,通过物相转化可磁选回收炉渣中的铁。The chemical composition,structural and morphological characterizations of a wa ter-quenched slag from copper smelting reverberatory furnace was studied in deta il by using X-ray fluorescence spectrometer （XRF）,X-ray diffraction （XRD）,scanni ng electron microscope （SEM） coupled with energy dispersive spectroscope （EDS）,hermogravimetric apparatus （TG）,differential scanning calorimeter （DSC）,Mossbauer spectroscope and metallographic microscope.The results obtained by metallographic microscopic analysis and SEM-EDS showed that the main phase compositions of the slag were fayalite,magnetite,copper matte and amorphous glass body.By XRD and Mossbauer spectroscope it was found that the iron primarily mainly consisted in fayalite,the slag only contained a little of magnetic iron oxides.The beneficia bility analysis demonstrated that the cupper in the slag will be able to be reco vered by fine grinding and flotation,and the iron in the slag will be able to be recovered by phase transformation and magnetic separation.
