Rare earths are essential constituents of more than 100 mineral species and present in many more through substitution. They have a marked geochemical affinity for calcium, titanium, niobium, zirconium, fluoride, phosphate and carbonate ions. Industrially important minerals, which are utilized at present for rare earths production, are essentially three, namely monazite, bastnasite and xenotime.
Pure beryllium is an extremely light, strong and brittle metal. With a density of 1.85g/cm 3, beryllium is the second lightest elemental metal, behind only lithium . The grey-colored metal is valued as an alloying element because of its high melting point, resistance to creep and shear, as well as its high tensile strength and flexural rigidity.

Although both beryllium and its compounds display high toxicity, little attention has been focused on the removal of beryllium from wastewaters. In this research, magnetically modified biochar obtained from poor-quality wheat with two distinct FexOy contents was studied as a sorbent for the elimination of beryllium from an aqueous solution. The determined elimination efficiency was higher than ...

The extraction of beryllium from beryl ore is a cumbersome process because beryl ore is very inert in the sense that no mineral acids under the normal conditions of temperature and pressure attack it (except HF). The extraction process is further complicated due to the requirement of eliminating silica from the reaction products.
