Barium. Barium (Ba) is obtained chiefly from the mineral barite. Barium is a soft, silvery, reactive metal. Because barium is so dense it is commonly used in some alloys, for example in spark plugs and ball bearings. As of 2013, China, India and Morocco were the world''s largest producers of barium.
Emerald is a form of beryl, the principal mineral of beryllium. Beryl, One of its uses is as a reducing agent in the separation of other metals from ore, The alkaline earth metal oxides are formed from the thermal decomposition of the corresponding carbonates.
Purdue University :: Inductively Coupled Plasma Optical
Inductively Coupled Plasma Optical Emmisions Spectrometer Preparation. Summary The Inductively Coupled Plasma Optical Emission Spectrometer (ICPOES) is used for elemental analysis of the sample material. We analyze the sample after the mineral separation procedure. This is done to tell if the sample is clean enough for beryllium and aluminum separation.
II. STAGES OF MINERAL EVOLUTION. STAGE 1. While an exact division of geological history into stages of mineral evolution is somewhat arbitrary, we propose that Earth''s mineral evolution can be divided into at least ten stages, each of which increased the mineral diversity of the planet.

Mineral evolution is a recent hypothesis that provides historical context to mineralogy postulates that mineralogy on planets and moons becomes increasingly complex as a result of changes in the physical, chemical and biological environment.
The metal beryllium is mined by its extraction from the beryl ores. It does not occur free in nature. The mining of raw minerals such as bertrandite ore and beryl ore from the Earth''s crust and volcanic rocks is required. Apart from beryl, beryllium is found in the mineral bertrandite, has become a major ore of the metal in the recent years.
