Scandium is a critical metal in increasing demand for modern technologies, such as light-
weight aluminum-scandium alloys. Evaluating current and identifying new sources of the …

The karst bauxites of the Parnassos-Ghiona Unit (Greece) are hosted within Upper Jurassic
to Late Cretaceous carbonate rocks. Three bauxite horizons are intercalated within shallow …

Bauxite and bauxite residue, a by-product of alumina production, were studied using a
combination of microanalytical techniques—electron microprobe wavelength dispersive …

This study analyzes the leaching behavior of elements from red mud (bauxite residue) at pH
values ranging from 2 to 13. The leaching characteristics of metals and contaminated anions …

Abstract In the Irano–Himalayan karst bauxite belt, in northwestern Iran, karst bauxite
orebodies are widespread. Although several of these orebodies have been characterized …

More recent data of Greek bauxites from the Parnassos-Ghiona active mines prove that rare
earth elements (REEs) occur mainly in the form of authigenic/diagenetic LREE 3+ carbonate …

Mediterranean-type bauxite deposits in Sardinia formed during the Upper Cretaceous
(Cenomanian–Turonian) due to the emergence of the south European margin of the Alpine …

More than five billion tons of karstic bauxites were formed in the North China Craton (NCC)
during the Late Carboniferous period. Compared to the bauxite ore, the genesis of the entire …

The Kolijan bauxite deposit (southeast Mahabad, northwestern Iran) mainly contains
aluminum-bearing iron ores and was deposited in karstic depressions and sinkholes of the …

In the late Triassic–early Jurassic Nasr-Abad deposit, bauxite ores are bauxitic iron ore and
Fe-rich bauxite, grading into bauxite and clayey bauxite upward the succession. The ores …
