Bayer process - Wikipedia

OverviewProcessWasteHistorySee also

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al2O3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be further purified before it can be refined into aluminium.

拜耳法（英語：Bayer process）是一种工业上广泛使用的从铝土矿生产氧化铝的化工过程。1887/由奥地利工程师卡尔约瑟夫拜耳（英语：Carl Josef Bayer）发明，其基本原理是用浓氢氧化钠溶液将氢氧化铝转化为铝酸钠，通过稀释和添加氢氧化铝晶种使氢氧化铝重新析出，剩余的氢氧化钠溶液重新用于处理下一批铝土矿，实现了连续化生产。今，世界上95%的铝业公司都在使用拜耳法生产氧化铝。
