Bauxite - an overview | ScienceDirect Topics The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide The bauxite is the primary source of aluminum to make cement that used for construction Aluminum is used for transport carrier, consumer durables, packaging, electrical, machinery equipment, refractory bricks, and abrasives
Bauxite - an overview | ScienceDirect Topics Bauxite is an aluminum ore that is widely recognized as one of the primary sources of aluminum It consists of various minerals mixed together, including boehmite, gibbsite, and diaspore, along with other compounds Bauxite is extracted and refined using processes such as the Bayer process to produce alumina, which is then used to manufacture aluminum AI generated definition based on
Provenance and genesis of karstic bauxite deposits in China . . . Karstic bauxite deposits that formed during the five levels have different sources, controls, and ore-forming processes However, the current provenances and processes of karstic bauxite deposits of all five levels, which are primarily based on detrital zircon and mercury isotope analyses, remain unclear
Research progress on the enrichment of gallium in bauxite In karstic bauxite, Ga predominantly existed in the form of isomorphism in aluminum minerals with small proportion of ion adsorption form on major minerals This review intends to provide general knowledge for the research progress on the occurrence state and enrichment mechanism of Ga in bauxite, and to induce a prospection for future work
A comparative review of the mineralogical and chemical composition of . . . The main goal of this work is to analyse the mineralogical and geochemical characteristics of bauxite deposits from some prominent bauxite producing and exporting countries of Africa in order to fashion out if a trend exist for the type of source rocks
Bauxite residue issues: II. options for residue utilization Worldwide bauxite residue disposal areas contain an estimated 2 7 billion tonnes of residue, increasing by approximately 120 million tonnes per annum The question of what to do with bauxite residue arose with the development of the Bayer process for alumina refining and the recognition that it generated a large amount of waste material In the subsequent 120 years, residues have been
