“…Wet scrubbers have been shown to be reliable for a variety of fuels and have been widely commercialized in industry for achieving SO 2 removal in excess of 95% . However, this kind of technology generates a large amount of wet solid waste, requires treatment of waste water and involves a complicated configuration and costly operation …”

Various studies have been increasingly performed on the reduction of sulfur content of iron ores and concentrates. The presence of sulfur in these materials causes technical problems in steel and alloys and environmental issues in the sintering of iron ore process. The achievement of higher sulfur removal rates has been an important goal since the development of sulfur removal techniques. In this research, an effort is made to separately introduce the various processes, industrial practices, and fundamental research activities to remove sulfur from iron ores, concentrates, or roasted iron ores. In this way, the optimized condition and latest innovations in sulfur removal using flotation are reviewed and the development of leaching and bioleaching techniques for sulfur reduction is introduced; following the development of thermal decomposition, physical separation methods, and magnetic separation technique are discussed. In each section, a brief introduction of fundamentals for the sulfur removal techniques and their potential advantages for sulfur removal are described and challenges for each technique are presented. Finally, the techniques are compared from technical, economic and environmental viewpoints, and future trends in desulfurization of iron ores are presented.

“…Spray dryers, which are representative of semi-dry FGD processes, have been extensively tested in America and Europe since 1970s [4][5][6][7][8]. Compared to wet scrubbers, this method does not require reheating energy and waste water treatment, thus allowing lower cost of operation [9][10][11].…”
