六十年代以来,世界各国都开始重视能源的节约,氧化铝生产也不例外,特别是西欧和日本,他们进行了很多研究也取得了一些明显的效果。目前在西方以三水铝石为原料用拜耳法生产氧化铝的总能耗一般在250～300万大 Since the 1960s, all countries in the world have begun to attach importance to energy conservation. Alumina production is no exception. In particular, Western Europe and Japan conducted many studies and achieved some remarkable results. At present, the total energy consumption of alumina produced by Bayer process using gibbsite in the west is generally 2.5-3 million
