摘要
2010年我国硫铁矿产能约16000kt/a[以w(S)35%标矿计],产量为15128.3kt,2006—2010年国内硫铁矿产量年均增长率为5.7%。2010年硫铁矿制酸产能为19000kt/a,产量为17720kt,2006—2010年硫铁矿制酸产量年均增长率为1.9%。"十一五"期间通过消化吸收和自主创新,我国硫铁矿制酸技术装备水平不断提升,在装置大型化、节能与热能回收利用、污染物减排、资源综合利用等方面取得了不俗的成绩,有效推进了硫酸工业的节能减排和循环经济发展。预测到"十二五"末期我国硫铁矿制酸产能将达到20000～22000kt/a,产量约16000kt/a,铁精粉产量有望达到4000kt/a。对今后加快淘汰落后产能、推广节能减排技术、促进资源综合利用、加强中、低温位热能回收利用等提出一些建议。
China＇s pyrite capacity reached 16 000 kt/a（as S 35 wt%） and production reached 15 128.3 kt in 2010 at an average annual growth rate of 5.7%during 2006-2010.China＇s pyrite-roasting sulphuric acid capacity reached 19 000 kt/a and production reached 17 720 kt in 2010 at an average annual growth rate of 1.9%during 2006-2010.China＇s technology and equipment in pyrite-roasting sulphuric acid production reached a new higher level through technical introduction and re-innovation.Great progress was made in larger-sized plants,energy saving and heat recovery,emission reduction and comprehensive utilization of resource,which effectively promoted the development of energy saving and recycling economy in China＇s sulphuric acid industry.It is predicted that the capacity will reach 20000-22000 kt/a and production will reach 16000 kt/a for pyrite-roasting sulphuric acid with resulted iron concentrate of 4 000 kt/a by the end of the Twelfth Five-Year Plan.Some suggestions are presented such as speeding up the elimination of backward production capacity,promoting technologies of energy saving and emission reduction and strengthening recovery and utilization of medium- and low-level heat energy recovery.
