Heavy Rare Earth Elements Yttrium

Heavy Rare Earth Elements Yttrium. Marine phosphorites are known to concentrate rare earth elements and yttrium (rey) during early diagenetic formation. When acetic acid is used as a mob …

A method was devised for preparing massive metallic yttrium, terbium, dysprosium, hohnium, erbium, and thulium in high purity and high yields by reducing the rare earth chloride or fluoride with calcium metal in tantalum containers in an inert atmosphere. Thus, an hplc method using acetic acid as novel eluent was explored for selective separation of yttrium form the heavy rare earth elements. Consequently, we initiated this study to determine if marine phosphorite deposits found in the global ocean host rey concentrations of high enough grade to be of.

Yttrium, whose atomic number is 39, is often included with the ree because of similar chemical properties.

Marine phosphorites are known to concentrate rare earth elements and yttrium (rey) during early diagenetic formation. Ahn et al., 2014 ; Marine phosphorites are known to concentrate rare earth elements and yttrium (rey) during early diagenetic formation. Much of the rey data available are decades old and incomplete, and there has not been a systematic study of rey distributions in marine phosphorite deposits that formed over a range of oceanic environments.

Are there any heavy rare earth metals in the world?

These elements are often subdivided into two groups:
