    Bauxite - Wikipedia

    Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin.

    Bauxite Beneficiation Flotation Silica Iron

    Although proven reserves of bauxite are expected to last for many years, the quality of the reserves that can be economically accessed is declining. For refiners, who are in the business of processing bauxite to make alumina, and eventually aluminum metal, this is a challenge with both financial and environmental implications.

    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.

    Mining and Refining Process - World Aluminium

    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.

    Decreasing Yield and Alumina Content of Red Mud by

    Bauxite produces 60-120 million tons of toxic red mud annually during its processing to alumina. Thus, in this , the modeling of the bauxite processing process to reduce quantity of red mud produced and with low alumina content was envisaged.

    ARTICLE: Addressing the Challenge of Bauxite Residue

    Mar 11, 2019  Bauxite ore contains 30-60% aluminum oxide (Al 2 O 3). In the Bayer process (Figure 2), the bauxite is digested in a pressure vessel along with a sodium hydroxide solution (caustic soda) at an elevated temperature, which dissolves the aluminum oxide converting it into sodium aluminate, leaving insoluble red mud solids as a by-product.
