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
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
Mapping the research landscape of bauxite by-products (red mud): An . . . Due to its high demand, bauxite, the primary ore from which aluminium is extracted, is now classified as a critical material in the EU and the US, given the potential risk of supply shortages for essential applications Geographical and production challenges surround bauxite, presenting geo-economic and environmental challenges
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
Global spatio-temporal variations and metallogenic diversity of karst . . . Bauxite, as an important ore of aluminum, forms through intense chemical weathering under warm and humid climate They are categorized based on tectonic setting, substrate and genesis as: 1) lateritic bauxites derived by in situ lateritization of underlying aluminosilicate rocks, and the majority occur in stable platform areas; and 2) karst bauxites developed on eroded surface of carbonate
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 - an overview | ScienceDirect Topics Bauxite is the most common aluminum ore Approximately 98% of primary aluminum production is based on bauxite In the former Soviet Union, aluinite and kaolinite are also used in small proportions for aluminum production Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals plus various mixtures of silica, iron oxide, titania
Climatic and hydrologic controls on upper Paleozoic bauxite deposits in . . . During the late Paleozoic, high-frequency eustatic fluctuations caused by waxing and waning of Gondwana icesheets controlled sedimentation in these coastal depositional systems, leading to cyclic accumulation of coal and bauxite deposits and cycles of vadose- and phreatic-type bauxite formation
