摘要
有色金属冶炼渣具有成分复杂、环境危害大等特点,属大宗工业固体废物,其综合利用是固体废物处理处置的难点.本文综述了有色金属冶炼渣中典型的铜冶炼渣、赤泥、镁冶炼渣、铅锌冶炼渣、锂渣的特性,并对有色金属冶炼渣脱硫脱硝的可行性进行了分析;总结了镁冶炼渣湿法脱硫和赤泥脱硫脱硝一体的工艺流程方法,同时列举了其它冶炼渣干湿法脱硫脱硝的应用.最后对有色金属冶炼渣进行综合利用的前景进行了展望.
Non-ferrous metal smelting slag has the characteristics of complex composition and environmental hazard. It is the staple industrial solid wastes, and its comprehensive utilization is a difficult task in solid waste treatment and disposal. In this paper, the characteristics of typical copper smelting slag, red mud, magnesium smelting slag, lead zinc smelting slag and lithium slag in non-ferrous metal smelting slag are reviewed, and the feasibility of desulfurization and denitrification of non-ferrous metal smelting slag is analyzed. The process flow method of magnesium smelting slag wet desulfurization and red mud desulfurization and denitrification is summaried, and the application of other smelting slag dry and wet desulfurization and denitration is also listed. Finally, the prospect of comprehensive utilization of non-ferrous metal smelting slag is prospected.
