中国五矿有色金属公司有关人士预测,为满足电解铝产能要求,今年我国需要氧化铝近1100万吨,国内自给近600万吨,供需缺口近500万吨。国内氧化铝供应存在一定垄断性,中国铝业公司下属六大氧化铝企业年产量在500-600万吨,严重供不应求。中铝公司已计划在2005年将氧化铝的年产能提高到约680-730万吨,但届时国内电解铝 China Minmetals Nonferrous Metals Company forecast that in order to meet the requirements of electrolytic aluminum capacity, China needs nearly 11 million tons of alumina and nearly 6 million tons of domestic self-supplied materials this year. The gap between supply and demand is nearly 5 million tons. There is a certain monopoly of domestic alumina supply, Aluminum Corporation of China under the six annual alumina production in 500-600 million tons, a serious shortage of supply.
