2011年国内氧化铝自给率提升根据中国有色金属工业协会公布的数据,2011年中国氧化铝产量为3407.8万吨,同比增长17.7%。2011年氧化铝产量增长较多的省份有山西、重庆和贵州。山西省产量增长主要是由于锦江集团140万吨/年新建产能的投产,贵州省的增长主要来自遵义铝业80万吨/年新建产能的达产,而重庆的增长主要是中铝新建的80万吨/年产能的逐步达产以及南川先锋氧化铝30万吨/年扩产产能的投产。截至2011年底,我国氧化铝产能为4747万吨/年,到2012年底还将有794万吨/年新增产能投产。
Domestic alumina self-sufficiency rate in 2011 According to data released by China Non-Ferrous Metals Industry Association, China’s alumina output in 2011 was 34.078 million tons, up 17.7% over the same period of last year. In 2011, the provinces where alumina production increased more are Shanxi, Chongqing and Guizhou. The increase in output of Shanxi Province was mainly attributed to the commencement of production of 1.4 million tons / year of new production capacity of Jinjiang Group. The growth of Guizhou Province mainly came from the new production of 800,000 tons / year of new capacity of Zunyi Aluminum, while the growth of Chongqing was mainly the newly-built 80% Production capacity of 10,000 tons / year and production of Nanchong Pioneer Alumina 300,000 tons / year Expansion capacity will be put into operation. As of the end of 2011, China’s alumina production capacity of 47.47 million tons / year, by the end of 2012 there will be 7.94 million tons / year new production capacity.
