Spodumene is a pyroxene mineral consisting of lithium aluminium inosilicate - LiAl(SiO₃)₂ - and is a source of lithium. Solubility is the characteristic Physical property referring to the ability of a given substance the Solute, to dissolve in a Solvent. Tenebrescence, also known as reversible Photochromism, is the ability of minerals to change colour when exposed to sunlight In Gemology, chatoyancy (or chatoyance) is an optical reflectance effect seen in certain Gemstones Coined from the French "oeil de chat" Fluorescence is a Luminescence that is mostly found as an Ultraviolet ( UV) light is Electromagnetic radiation with a Wavelength shorter than that of Visible light, but longer than X-rays The pyroxenes are a group of important rock-forming Silicate minerals found in many Igneous and metamorphic rocks.

Crystals form in the monoclinic system and are typically heavily striated parallel to the principal axis. In Crystallography, the monoclinic Crystal system is one of the 7 lattice Point groups A crystal system is described by three vectors. Crystal faces are often etched and pitted with triangular markings.

Spodumene is derived from the Greek spodumenos (σποδυμενος), meaning "burnt to ashes," owing to the opaque, ash-grey appearance of material refined for use in industry. Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly

Spodumene occurs in lithium rich granites and pegmatites. Granite (ˈɡrænɪt is a common and widely occurring type of intrusive, Felsic, igneous rock. Pegmatite is a very coarse-grained Igneous rock that has a grain size of 20 mm or more such rocks are referred to as pegmatitic.

Economic importance

Spodumene is an important source of lithium for use in ceramics, mobile phone and automotive batteries, medicine and as a fluxing agent. The word ceramic is derived from the Greek word κεραμικός ( keramikos) The automotive industry is the industry involved in the design development manufacture marketing and sale of Motor vehicles In 2007 more than 73 million motor vehicles In electronics a battery is a combination of two or more Electrochemical cells which store chemical Energy which can be converted into electrical energy Medicine is the art and science of healing It encompasses a range of Health care practices evolved to maintain and restore Human Health by the Lithium is extracted from spodumene by fusing in acid. In Computer science, ACID ( Atomicity Consistency Isolation Durability) is a set of properties that guarantee that Database transactions are

World production of lithium via spodumene is around 80,000 metric tonnes per annum, primarily from the Greenbushes pegmatite of Western Australia, and some Chinese and Chilean sources.

In Chemistry, an alkali (from Arabic: Al-Qaly القلي القالي) is a basic, ionic salt of an Alkali metal For a topic outline on this subject see List of basic Argentina topics. Lithium chloride is a Chemical compound with the formula Li[[Chlorine Cl]] Lithium chloride is converted to lithium carbonate and lithium hydroxide by reaction with sodium carbonate and calcium hydroxide respectively.

Kunzite

Kunzite
See the pleochroism and the tipical etched marks (unknown scale)

Kunzite is a pink to lilac colored gemstone, a variety of spodumene with the color coming from minor to trace amounts of manganese. A gemstone or gem, also called a precious or semi-precious stone, is a piece of attractive Mineral, which &mdash when cut and polished &mdash Manganese (ˈmæŋgəniːz is a Chemical element, designated by the symbol Mn. Some (but not all) kunzite used for gemstones has been heated to enhance its color. It was named in honor of New York mineralogist and gemologist George Frederick Kunz. George Frederick Kunz ( September 29, 1856 – June 29, 1932) was an American Mineralogist. It has been found in Brazil, USA, Canada, CIS, Mexico, Sweden, Western Australia, Afghanistan and Pakistan. |utc_offset = -2 to -4 |time_zone_DST = BRST |utc_offset_DST = -2 to -5 |cctld Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page The United Mexican States ( or commonly Mexico (ˈmɛksɪkoʊ () is a federal constitutional Republic in North America.
