Italy has no record of Li production, even though it is well known for its outstanding Li
mineral specimens from the Elba Island pegmatites. Because of the current geopolitical …

Rare earth elements and yttrium (REY) have gained greater attention for being largely used
in various high-tech applications and green energies. Recently, supply shortage and high …

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

Bauxite is a prominent constituent of the paleoweathering crust that formed during a~ 150-
million-year-long interval between the Ordovician and Late Carboniferous on the North …

In the last few years, many efforts have been devoted to the factors controlling the
distribution of CMs in karst bauxites, residual deposits hosted in carbonate rocks. Most of …

Bauxites are an excellent indicator of tropical palaeoclimate and subaerial exposure in the
geologic record, where the study of their structures, textures, mineralogy, geochemistry, and …

Recent studies indicate that volcanism may be a potentially important factor in the formation
of karstic bauxite, but more evidence is needed. Six billion tons of bauxite formed upon …

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 …

The present study focuses on the geochemistry and occurrence of REY (rare earth elements
and yttrium)-bearing minerals in the Late Cretaceous karst bauxite deposits in the central …

The growing gap in the supply and demand of rare earth elements (REEs) calls for the
recovery and reuse of REEs from waste streams and secondary sources like e-waste. The …
