MAGNESIUM ORES

Magnesium is a chemical element with the symbol Mg, atomic number 12 and common oxidation number +2. It is an alkaline earth metal and the eighth most abundant element in the Earth's crust, where it constitutes about 2% by mass,[2] and ninth in the known Universe as a whole.[3][4] This preponderance of magnesium is related to the fact that it is easily built up in supernova stars from a sequential addition of three helium nuclei to carbon (which in turn is made from three helium nuclei). Magnesium ion's high solubility in water helps ensure that it is the third most abundant.




Detailed description:
Magnesium is the 11th most abundant element by mass in the human body; its ions are essential to all living cells, where they play a major role in manipulating important biological polyphosphate compounds like ATP, DNA, and RNA. Hundreds of enzymes thus require magnesium ions to function. Magnesium is also the metallic ion at the center of chlorophyll, and is thus a common additive to fertilizers.[6] Magnesium compounds are used medicinally as common laxatives, antacids (i.e., milk of magnesia), and in a number of situations where stabilization of abnormal nerve excitation and blood vessel spasm is required (i.e., to treat eclampsia). Magnesium ions are sour to the taste, and in low concentrations help to impart a natural tartness to fresh mineral waters.

The free element (metal) is not found naturally on Earth, as it is highly reactive (though once produced, is coated in a thin layer of oxide (see passivation), which partly masks this reactivity). The free metal burns with a characteristic brilliant white light, making it a useful ingredient in flares. The metal is now mainly obtained by electrolysis of magnesium salts obtained from brine. Commercially, the chief use for the metal is as an alloying agent to make aluminium-magnesium alloys, sometimes called "magnalium" or "magnelium". Since magnesium is less dense than aluminium, these alloys are prized for their relative lightness and strength.

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...

COLUMBITE[(Fe, Mn)Nb2O6]

Columbite , also called  niobite ,  niobite-tantalite  and  columbate  [( Fe ,  Mn ) Nb 2 O 6 ], is a black  mineral  group that is an ore of  niobium . It has a submetallic  luster  and a high density and is a niobate of  iron  and  manganese .  Detailed description This mineral group was first found in  Haddam, Connecticut , in the United States. It forms a series with the  tantalum -dominant analogue  ferrotantalite  and one with the manganese-dominant analogue  manganocolumbite . The iron-rich member of the columbite group is  ferrocolumbite . Some tin and tungsten may be present in the mineral.  Yttrocolumbite  is the yttrium-rich columbite with the formula (Y,U,Fe)(Nb,Ta)O 4 . It is a radioactive mineral found in  Mozambique . Columbite has the same composition and crystal symmetry ( orthorhombic ) as  tantalite . In fact, the two are often grouped t...

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".   Physical Properties of Arsenopyrite Chemical Classification sulfide Color silver white to steel gray Streak dark grayish black Luster metallic Diaphaneity opaque Cleavage poor Mohs Hardness 5.5 to 6 Specific Gravity 5.9 to 6.2 Diagnostic Properties smells like garlic when crushed, crystal form Chemical Composition iron arsenic sulfide, FeAsS Crystal System monoclinic Uses poison...
