What mineral class does NaCl belong to? NaCl is otherwise known as the compound sodium chloride. It is classified as a halite (in the Halide group), which is sodium chloride (or rock salt) in mineral form.
Carbon polymorph group minerals are elements which exist in more than one crystal forms. Various minerals such as graphite and diamond belong to the carbon polymorph group which are widely used in the in various industries such as agrochemicals, pharmaceuticals, and foods among others.
Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.
Minerals. A mineral, by definition, is any naturally (not manmade) occurring, inorganic (not a result of life plant or animal) substance. Its chemical structure can be exact, or can vary. All minerals belong to a chemical group, which represents their affiliation with certain elements or compounds. The classified chemical groups are known as:
Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).
However, all mineral reference guides list it together with other minerals. Limonite is a matrix base of many other minerals, and the term gossan is used as a reference to Limonite when it is used as a a matrix for another mineral or has formed an undesirable staining on top of it.

Kaolinite, which is named for its type locality, Kao-Ling, Jianxi, China; is a common phyllosilicate mineral. It lends it name to the Kaolinite Group, members of which also belong to the larger general group known as the Clays. Kaolinite's structure is composed of silicate sheets (Si 2 O 5) bonded to aluminum oxide/hydroxide layers (Al 2 (OH) 4) called gibbsite layers.
Feldspar. Feldspar is the name given to a group of minerals distinguished by the presence of alumina and silica (SiO 2) in their chemistry.This group includes aluminum silicates of soda, potassium, or lime.
Dec 30, 2012· Diamond is not considered a rock forming mineral. The group of minerals that diamond belongs to is called native elements. Other members of this group are gold, platinum, and copper - none of this group is a rock forming mineral.
What remains is a nearly pure carbon material that crystallizes into mineral graphite. This graphite occurs in "seams" that correspond to the original layer of coal. When mined, the material is known as "amorphous graphite." The word "amorphous" is actually incorrect in this usage, as it does have a crystalline structure.
Oct 14, 2008· Best Answer: Alexandrite belongs to the Oxides mineral group. ... Alexandrite is a highly pleochroic variety of the mineral Chrysoberyl: BeAl2O4. which crystallises in the orthorhombic system. ... Graphite is an element. It is made of carbon. Other elements that are found in nature are copper, silver and gold, but they are metals and carbon ...
Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties.
1.1.1 Silica group. Minerals that belong to this group share the same chemical composition — SiO 2. By far the most important mineral in this group is quartz. Quartz ... Occurrence: Graphite is a common mineral in some metamorphic rocks (graphite schist, slate, phyllite) that originally as sediments contained organic matter. Graphite also ...

A mineral is a naturally occurring chemical compound, usually of crystalline form and not produced by life processes.A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids.The study of minerals is called mineralogy.. Minerals are classified by variety, species, series and group, in order of increasing generality.
The only common mineral that has properties similar to pyrite is marcasite, a dimorph of pyrite with the same chemical composition but an orthorhombic crystal structure. Marcasite does not have the same brassy yellow color of pyrite. Instead it is a pale brass color, sometimes with a slight tint of green.
