Aluminum Mineral Processing and Metallurgy: IronRich

Bauxite is the main source for alumina production With the rapid development of iron and steel industry and aluminum industry, highquality iron ore and bauxite resources become increasingly tense However, a lot of ironrich bauxite and Bayer red mud resources have not been timely and effectively recycled, resulting in serious problems of environmental pollution and wastage of resources

Extraction Process of Aluminium from Bauxite Ore

Composition

Mining and Refining – Process

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process) Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters The

Mining and Refining – Process bauxiteworldaluminium

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting Beneficiating ore
