摘要
2009年我国10种主要有色金属总产量为26 048.8 kt,同比增长4.0%;冶炼烟气制酸产量(以H_2SO_4计)17785 kt,同比增长15.3%。近年来我国铜、镍、铅、锌冶炼新技术得到推广应用,节能、降耗、减排效果显著,冶炼烟气制酸在高浓度SO_2烟气制酸、低浓度SO_2烟气回收SO_2及装置大型化等方面取得技术进步。今后2年我国有色金属特别是铜的产量增长幅度较大,预计未来几年我国冶炼烟气制酸总产量将达到30 000 kt/a。
China＇s 10 kinds of main nonferrous metals production increased by 4.0%to 26 048.8 kt and metallurgical acid production（as H_2SO_4） increased by 15.3%to 17 785 kt in 2009.In recent years,new smelting technologies for copper,nickel,lead and zinc have been adopted widely in China and remarkable results of saving energy,reducing consumption and emission were obtained.Important technological progress was made in metallurgical acid production including producing sulphuric acid with high SO_2 concentrations off-gases,recovering SO_2 from low SO_2 concentrations off-gases and plant enlargement.In the next two years,China＇s nonferrous metals, especially,copper production will be largely growing.It is predicted that metallurgical acid production will reach 30 000 kt/a in the next few years.
