Studies on Metal Flow from Khondalite to Bauxite to ...

Alumina is produced from khondalite hosted bauxite of Indian origin in the Alumina refinery employing the time tested Bayer’s Process. In the process, about 40% of unwanted elements are rejected as undigested sand and red mud. During the whole cycle; major, minor, trace and RE elements in these litho-units get redistributed, either depleted or enriched. Khondalite, the source rock of bauxite ...

The Rare Earth Elements Potential of Greek Bauxite Active ...

A trend similar to REE geochemical trend also stands for most of the trace elements that are present in Greek bauxites—mainly HFSE—except for LILE. Besides, Greek bauxite metallurgical residue’s (red mud) REE content seems to be remarkably increased by almost two times compared to that of the Parnassos-Ghiona bauxite parent material. Scandium is another critical element. In the studied ...

Determination of Trace Elements in Bauxite Using Laser ...

Quantification of trace element contents in bauxite by solution ICP‐MS and other analytical methods that rely on conventional dissolution techniques can be challenging, because the refractory nature of common host minerals complicates complete digestion.

RARE EARTH ELEMENTS IN KARST-BAUXITES: A NOVEL

Rare earth elements (REE) become concentrated in the bauxite deposits due to crystallisation of authigenic REE-bearing minerals, accumulation of residual phases and the adsorption of ions on clays and other mineral surfaces.

Rare Earth Element Phases in Bauxite Residue - mdpi

The quality of trace element analysis was assessed by analysing standard bauxite reference material BX-N for both methods (ICP-MS and INAA). In the case of ICP-MS, higher than suggested deviations were detected in lanthanum, praseodymium, dysprosium and erbium concentrations, and the rest of the element concentrations were within acceptable limits. Mineralogical composition was determined by X ...

Mining and Refining – Bauxite Residue Management

Like most ores and soils, bauxite can contain trace quantities of metals such as arsenic, beryllium, cadmium, chromium, lead, manganese, mercury, nickel and naturally-occurring radioactive materials, such as thorium and uranium. Most of these trace elements remain with the residue after extraction of
