The “coal–bauxite–iron” structure in the ore-bearing

2013-9-1  The middle deposition of the bauxite layer in the ore-bearing rock series is neritic/littoral facies sandstone. The minerals include mainly diaspore and kaolinite. The variegated bauxite contains hematite and becomes red upon oxidation, indicating that the water body is in an oxidizing environment.

The “coal–bauxite–iron” structure in the ore-bearing

The Yudong bauxite deposit is located in the Kaili–Huangping bauxite-concentrated area, in south-eastern Guizhou Province, China. The ore-bearing rock series consists of the lower part (Fe-bearing member) and middle part (Al-bearing member) of the Middle Permian Liangshan Formation, covering the Upper Devonian Gaopochang Formation.

Mineralogical characteristics of the karstic bauxite

Based on the textural features and iron abundances, the bauxite ores occurring in the middle segments are divided into three types of ores—clastic, compact, and high-iron. The bauxite ores primarily comprise diaspore, boehmite, kaolinite, illite, and hematite with minor zircon, pyrite, rutile, and feldspar.

Mineralogical characteristics of the karstic bauxite

2015-3-1  After investigation of the Al-bearing rock series in Guizhou, Guangxi, Henan, and Yunnan provinces, we determined that bauxite deposits are frequently associated with the iron-rich stratum and coal seams that formed a “coal–bauxite–iron” special structure, which were also prevalent in karst deposits in other countries, such as the Ghiona bauxite deposit in Greece (Kalaitzidis et al., 2010), the Nurra bauxite deposit in Italy (Mameli et al., 2007), and the Kanisheeteh bauxite deposit

Electrolytic Iron Production from Alkaline Bauxite Residue

Bauxite ore is treated within the Bayer process to produce metallurgical grade alumina which is the raw material for aluminium production. Bauxite ore depending on its origin contains 40–60% alumina and the rest is a mixture of iron (20–30%), silicon and titanium oxides.

2012-9-27  The iron ore minerals (hematite and goethite) are 10-50microns in size and are disseminated throughout the oolitic and pisolitic bauxitic minerals. At places the goethite exhibits colloform texture. The preservation of basaltic texture in some of the samples indicate that the insitu nature of these bauxites, which are formed by the alteration of calcic plagioclase from the parent basalt.

Electrolytic Iron Production from Alkaline Bauxite

2021-6-3  In general, due to its high alkaline (Na 2 O ≈ 10%) and its titanium (TiO 2 ≈ 4–15%) content, bauxite residue is not suitable for use as an iron ore substitute in blast furnaces. Bauxite residue reductive smelting processes can be applied by several technologies (Corex, Finex ®,HIsmelt, Romelt, AusIron and electric arc furnace (EAF)) for the production of pig iron ( 10,11 ).
