Beryllium in History: Prior to any major developments in beryllium refining, it was known all the way back to ancient Egyptian. It was found along with emeralds but taken as a completely different element and discarded completely. Beryllium was first discovered as an unknown element that was common to beryl.

An electrolytic process of refining beryllium that would roduce material sufficiently pure for nuclear engineering applications was investigated. Nickel strip cathodes and commercial grade beryllium anodes were used. To avoid contamination by chlorine, an electrolyte of KF - NaF 2 BeF2 was first tried.

Carbon, hydrogen, nitrogen, oxygen--the famous elements atop the periodic table steal all the headlines. At the far end, in the table's highest numbers, lie unstable elements that only exist for fractions of a second before they radioactively decay.

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 ...

Introduction. Lithium mineralisation hosted by spodumene-bearing pegmatites has long been known in Western Australia, notably at the giant Greenbushes deposit in the State's south-west which has a long history of production dating back to 1888 (Partington et al. Citation 1995), first for tin and tantalum, and now lithium.Similarly, lithium-bearing pegmatites …

Sources of Beryllium. Beryllium is the first member of the alkaline earth family of elements, which means that it's highly reactive and easily bonds to form compounds but is difficult to separate into a pure metal. Beryllium was discovered by Louis-Nicolas Vauquelin in 1798 as a component of beryl and in emeralds.
