Introduction. The rare earth elements (REEs), which include the lanthanide elements (Z=57 through 71), are so called because most of them were originally isolated in the 18th and 19th centuries as oxides from rare minerals (Kabata-Pendias and Pendias, 2001).They are fractionated during the crystallization of minerals from magma and …

The term "rare metals" refers in this work to metals with a low availability in natural. Based on their chemistry, rare metals were classified into; 1) rare earth elements (La-Lu), 2) trace elements (Nb, Ta, Mo, Cu, Ni, Co, Sn, W, V), 3) noble elements (Au, Ag, and PGE) and 4) fissionable elements (U and Th). In Egypt, rare earth elements occur in the …

Egypt Salt. Ancient Egyptian deserts have been found in some of the mummies preserved in salty sand (consisting of a mixture of salt and nitron) dating back to 3000 BC. This, although evidenced by the knowledge of the benefits of salt in conservation since the time of the Pharaohs. However, some historians see that the ancient …

In Egypt, rare metal-bearing granites are the host of many strategic metals such as Nb and Ta, in addition to Mo and U mineralization (e.g., Helba et al., 1997;Osmond et al., 1999; El Kammar et al ...

G: 3.1cm x 2.8cm x 2.6cm. This is a piece of Prophecy Stone, also called Z Stone, from White Desert, north of the Farafra Oasis in New Valley, Egypt. Prophecy stone is a fairly rare mineral, with only a few deposits of it having been found. It is a Goethite and Limonite psuedomorph after Marcasite, meaning the marcasite formed first and then ov.

In the Eastern Desert of Egypt, these granites are called rare-metal granites. The Nuweibi intrusion, the target of the present work, is one of the most outstanding examples of rare-metal bearing granite in the ANS. It contains the largest ore reserve of Nb Ta oxide minerals in the Eastern Desert of Egypt. The published works about this ...

A man named Barbosa (not the pirate captain but with just as much booty) discovered the Paraiba Tourmaline stones in 1989, making this one of the most recently discovered rare minerals. These crystals are known for their vibrant Blue-Green hue. Though primarily sourced from Brazil, they have also been found in Nigeria.

The granite is characterized by an agpaitic mineral sequence in which alkali pyroxene (aegirine) and amphibole (riebeckite) are late crystallizing phases. Accessory minerals are represented by zircon, apatite, pyrochlore, and Fe-Ti oxides. Zircon occurs as interstitial phase into aegirine crystals. It ranges in abundance from 0.05 to 0.2 vol%.

A mineral deemed critical today may not be so in the future if alternatives emerge or production expands. Today's critical minerals are primarily rare earth elements and metals that play central roles in advanced technological sectors, such as electric vehicles (EVs), renewable energy, electronics, and defense systems.
