Spodumene is from the Greek, spodoumenos, "burnt to ash," alluding to the ashy color of early specimens. Kunzite is named after the American gem expert, G. F. Kunz (18561932). Hi ddenite is named after the American mi
spodumene concentrates after roasting and acid roasting operations. A concentrate with at least 6% Li2O (approximately 75% spodumene) is suitable for roasting. Roasting is performed at about 1050°C, during which spodumene will go through a phase transformation from αspodumene to βspodumene. The αspodumene is virtually refractory to hot
Fine examples of spodumene are transparent, gem clear, and display lovely, even color, and many of the best and the largest examples are from Minas Gerais, Brazil and specifically, Lavra de Resplendor. In 1990, a significant pocket of seven hundred kilos of spodumene was recovered from the mine.
R.17E. contain significant white to very pale pink spodumene, usually in cleavable masses up to 2 cm. long. The spodumene is associated with quartz, K feldspar, cleavelandite, elbaite tourmaline, lepidolite, columbitetantalite and other rare minerals. It also freqeuntly alters to a mixture of clays and micas (Koehler, Steve,1989).

The mineral, spodumene (Li 2 O.Al 2 O 3.4SiO 2), is of primary interest for the commercial production of lithium in North America due to its availability and high potential yield of lithium oxide (Li 2 O). Large reserves of spodumene can be found in North Carolina in the United States and in Quebec and Manitoba in Canada.
Spodumene, a lithium aluminum silie mineral (LiAlSi2O6) in the pyroxene family, an important ore of lithium and a source of ceramic materials. It is ordinarily found in lithiumbearing granite pegmatites. When brilliant and glassy, clear spodumene is valued as a semiprecious gem (more by

Spodumene is a pyroxene mineral consisting of lithium aluminum inosilie.It has a vitreous luster and occurs in a range of colors. The purplish or lilac variety is called kunzite, and the yellowishgreen or emeraldgreen variety is known as hiddenite.Other crystals range from colorless to yellow. The crystals are often quite large.
Spodumene (Triphane) Introduction to Meaning and Uses of Spodumene. Spodumene is a lithium aluminum silie mineral usually found in pegmatite veins. In its natural opaque form, Spodumene is worked as a lithium ore and processed into different grades for use in ceramics, glass, batteries, steel, fluxing agents and medicine.
Spodumene is from the Greek word spodumenos which means burnt to ashes. This is a reference to its most common color. You will rarely find gray spodumene cut as gems, but the other colors can be spectacular. Kunzite is the pink variety of spodumene. It is primarily from Afghanistan.
Spodumene is a fairly prevalent mineral, but mostly dull and uninteresting in its most common forms. However, its two distinctly colored transparent varieties, Kunzite (pink) and Hiddenite (green) are very aesthetic and valued as gemstones. Hiddenite is much rarer than Kunzite, and can is highly valued, especially the deeper green color forms.
Spodumene is a rock forming mineral in granites and pegmatites that bear other lithium minerals. Spodumene is a relatively new mineral to science, being discovered in the last three centuries and gem varieties have only been discovered in the last 120 years.
Spodumene is a silie mineral often referred to as lithium feldspar. Its mineral form is characterized by hard needlelike grains of brilliant white color. It is used in ceramics as a source of lithia. Lithia is a very powerful flux, especially when used in conjunction with potash and soda feldspars. As one of
Spodumene has a vitreous luster, a hardness of 6.5–7 on Mohs'' scale, a density of 3,100–3,200 kg/m 3, and a perfect cleavage along the prism. When heated in the temperature range 950°l 100°C, natural αspodumene changes to the βmodifiion of the crystal structure (βspodumene).
Spodumene is a white to greyish mineral chemically a lithium aluminum silie LiAl(Si 2 O 6) occuring in granite pegmatites.Albemarle''s spodumene concentrates contain up to 7.2% lithium oxide (lithia) and have a low impurity profile.
As for it "swamping" the spodumene entry, tearing out the hiddenite component before the rest of the data on spodumene, kunzite and triphane was uploaded was downright silly. —Preceding unsigned comment added by Gemology (talk • contribs) 06:43, 10 December 2008 (UTC) Hiddenite is a color variety of spodumene, caused by chromium ion inclusions.
Kunzite is the bestknown variety of the mineral spodumene. It''s named after famed gemologist George Frederick Kunz, who was the first to identify it as a unique variety of spodumene. Kunzite gets its delie color from trace amounts of manganese. California''s San
