ARSENOPYRITE MINERAL

Listing description

What is Arsenopyrite?
Arsenopyrite is an iron arsenic sulfide. It is the most common arsenic mineral and the primary ore of arsenic metal.

Detailed description

Arsenopyrite is most often found as a hydrothermal vein mineral and sometimes as a mineral of contact metamorphism. It is sometimes referred to in old texts as "mispickel".

SPODUMENE [LiAl(SiO3)2]

Spodumene is a pyroxene mineral consisting of lithium aluminium inosilicate , Li Al ( Si O 3 ) 2 , and is a source of lithium. It occurs as colorless to yellowish, purplish, or lilac kunzite (see below), yellowish-green or emerald-green hiddenite , prismatic crystals, often of great size. Detailed d Single crystals of 14.3 m (47 ft) in size are reported from the Black Hills of South Dakota , United States . [5] [6] The normal low-temperature form α-spodumene is in the monoclinic system whereas the high-temperature β-spodumene crystallizes in the tetragonal system. The normal α-spodumene converts to β-spodumene at temperatures above 900 °C. [4] Crystals are typically heavily striated parallel to the principal axis. Crystal faces are often etched and pitted with triangular markings. Discovery and occurrence Spodumene was first des...

BERYLLIUM ORE

A divalent element, beryllium is found naturally only combined with other elements in minerals. Notable gemstones which contain beryllium include beryl ( aquamarine , emerald ) and chrysoberyl . The free element is a steel-gray, strong, lightweight brittle alkaline earth metal . It is primarily used as a hardening agent in alloys , notably beryllium copper . Structurally, beryllium's very low density (1.85 times that of water), high melting point (1287 °C), high temperature stability and low coefficient of thermal expansion, make it in many ways an ideal aerospace material, and it has been used in rocket nozzles and is a significant component of planned space telescopes. Detailed description Because of its relatively high transparency to X-rays and other ionizing radiation types, beryllium also has a number of uses as filters and windows for radiation and particle physics experiments. Commercial use of beryllium m...

SELENIUM ORE

Selenium (pronounced /s ɨ ˈl ɛ niəm/ si-LEN-ee-əm or /s ɨ ˈliːniəm/ si-LEE-nee-əm ) is a chemical element with the atomic number 34, represented by the chemical symbol Se , an atomic mass of 78.96. It is a nonmetal , chemically related to sulfur and tellurium , and rarely occurs in its elemental state in nature. Detailed description Isolated selenium occurs in several different forms, the most stable of which is a dense purplish-gray semi-metal ( semiconductor ) form that is structurally a trigonal polymer chain. It conducts electricity better in the light than in the dark, and is used in photocells (see section Allotropes below). Selenium also exists in many non-conductive forms: a black glass -like allotrope, as well as several red crystalline forms built of eight-membered ring molecules, like its lighter cousin sulfur. Selenium is found in economic quantities in sulfide ores such as pyrite , partially replacing the sulfur in the ore matrix. Minerals that are s...
