Rare-earth element - Wikipedia

The rare-earth elements (REE), also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly-indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides ...

Oxide - Wikipedia

An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O 2- (molecular) ion. with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials considered pure elements often develop an oxide coating. For example, aluminium ...

Characterization of Rare Earth Element Minerals in Coal Utilization ...

Rare earth elements (REE) in various forms (e.g., crystalline mineral phases; adsorbed/absorbed state on and into organic macerals, neoformed glass from flyash or bottom ash) from domestic feedstocks such as coal deposits to coal utilization byproducts (CUB) have the potential to reduce foreign REE dependence and increase domestic resource security.

Gold in iron oxide copper-gold deposits - ScienceDirect

IOCG deposits are a significant repository of gold in the world. However, the most of IOCG deposits characterized by low gold grades (ranging from 0.01 g/t to 1.41 g/t and averaging 0.41 g/t) relatively high tonnage (ranging from 0.6 to 483 t and averaging 64 t, but with the exception of the Olympic Dam containing 2968 t of gold metal). There ...

The most common elements present on Earth as free elements are oxygen and nitrogen, which make up 21% and 78% by mass of the dry atmosphere. Other free elements are argon (about 1% of the atmosphere), and the other so-called noble gases, helium, neon, krypton, xenon and radon, which are present in the atmosphere in trace amounts.

MIAC: the next big thing in Mineral Deposits? - Geology for Investors

In general, MIAC refers to hydrothermal deposits with extensive alteration dominated by iron, alkali elements (mostly sodium and potassium), and calcium. The minerals most commonly associated include hematite and magnetite (iron), albite, amphibole, K-feldspar, biotite, and illite (alkali), and epidote and calc-silicate minerals (calcium).

The formation of raw iron ore pellets are known as palletizing. It is another process of agglomeration in which fine grained moist ore is rolled in drum, so that the particles cling together and rollup into small, spherical pellets. Making larger spheres from the finely ground iron ore has several purposes.

This compares to the up to 3% of rare earth's that make up bastnäsite and monazite rare earth deposits. Scandium (Sc, 21) is another transition metal, which is in the same periodic group as yttrium. It is sometimes classed as a rare earth, and can occur in rare earth deposits. A main source is the Bayan Obo rare earth mine in China.
