氧化铝生产方法研究

Study on production methods of alumina

氧化铝生产就是从铝土矿中提取氧化铝的过程,自然界中铝矿石成分各异,为了有效降低氧化铝的生产成本,根据不同品质的铝土矿,对应采取不同的生产工艺方法,世界上目前大部分国家都选择碱法生产氧化铝,碱法中又以拜耳法、烧结法和联合法为主。

Alumina production is the process of extracting alumina from bauxite, chinalco nature different mineral composition, in order to effectively reduce the production cost of alumina, according to the different quality bauxite, corresponding to different methods of production technology, at present most countries in the world is to choose soda production of alumina, alkaline or in bayer process, sintering process and the combined method.
