The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef, the most important ore of aluminium, contains only 3060% aluminium oxide (Al 2 O 3), 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 ...
Q3._____ process is used purification of bauxite ore. A. Froth flotation B. Blast furnace C. Baeyer's Process Answer: C. Solution: Baeyer's Process is mostly used on bauxite ore with ferric oxide as the major contaminant. Because the ore is usually red in colour, it is known as red bauxite. Q4.

Recently I was taught how aluminium is commercially extracted. The ore is first concentrated by leaching either by Bayer's process for red bauxite (impurity: ce{Fe2O3}) or by Serpeck's process for white bauxite (impurity: ce{SiO2}). Then alumina is reduced electrolytically via HallHéroult's process directly to 99% pure aluminium.
