摘　　要：铁矿石脱硫对建设"绿色经济"的环境友好型社会及经济可持续性发展具有关键性意义。本文主要描述了铁矿石脱硫的各种工艺、工业实践和基础研究活动,包括以磁选工艺为主的物理法、以浮选工艺为主的物理化学法、以酸浸工艺为主的化学法及应用生物浸出对含硫物质进行脱硫的微生物法,总结了各种脱硫技术的优势与不足,并对未来铁矿石脱硫技术的研究提出建议。Desulfurization of iron ores is of great significance to the construction of "green economy" environment-friendly society and sustainable economic development. This paper mainly introduces various technologies, industrial practices and basic research activities of iron ore desulfurization, including physical method based on magnetic separation process,physical and chemical method based on flotation process, chemical method based on acid leaching process, and microbial method for desulfurization of sulfur-containing substances by bioleaching. The advantages and disadvantages of each desulfurization technology are summarized, and suggestions for future research on iron ore desulfurization technology are put forward.
