The mechanism of arsenic removal during a sintering process was investigated through experiments with a sintering pot and arsenic-bearing iron ore containing arsenopyrite; the corresponding chemical properties of the sinter were determined by inductively coupled plasma atomic emission spectrometry(ICP-AES),X-ray diffraction(XRD),and scanning electron microscopy(SEm) coupled with energy-dispersive X-ray spectroscopy(EDS). The experimental results revealed that the reaction of arsenic removal is mainly related to the oxygen atmosphere and temperature. During the sintering process,arsenic could be removed in the ignition layer,the sinter layer,and the combustion zone. A portion of Fe As S reacted with excess oxygen to generate Fe AsO_4,and the rest of the Fe As S reacted with oxygen to generate As_2O_3(g) and SO_2(g). A portion of As_2O_3(g) mixed with Al_2O_3 or CaO,which resulted in the formation of arsenates such as AlAsO_4 and Ca_3(AsO_4)_2,leading to arsenic residues in sintering products. The Fe As S component in the blending ore was difficult to decompose in the preliminary heating zone,the dry zone,or the bottom layer because of the relatively low temperatures; however,As_2O3(g) that originated from the high-temperature zone could react with metal oxides,resulting in the formation of arsenate residues.
