Release time:2016-07-05 Affiliation of Author(s):School of Minerals Processing & Bioengineering, Central South University Journal:JOM Abstract:Sn-, Zn-, and As-bearing iron ores are typical complex ores and are abundantly reserved in China. This kind of ore is difficult to use effectively due to the complicated relationships between iron and the other valuable metal minerals. Excessive Sn, Zn, and As contents would adversely affect ferrous metallurgy operation as well as the quality of the products. In this study, thermodynamic calculations revealed that it was feasible to synchronously volatilize Sn, Zn, and As via CO reduction. Experimental results showed that preoxidation was necessary for the subsequent reductive volatilization o Co-author:Tao Jiang, Yufeng Guo, Peidan Wen, Mingjun Rao, Yuanbo Zhang*, Zhixiong You, Guanghui Li Indexed by:Unit Twenty Basic Research Discipline:冶金工程学 Document Type:J Volume:66 Issue:9 Page Number:1701-1710 Translation or Not:no Date of Publication:2014-01-14 Links to published journals:http://xueshu.baidu.com/s?wd=paperuri%3A%28483733ef7d23120fe84612c3c5d40347%29&filter=sc_long_sign&tn=SE_xueshusource_2kduw22v&sc_vurl=http%3A%2F%2Flink.springer.com%2F10.1007%2Fs11837-013-0852-4&ie=u -
