Mineral Gallery - The Sulfates Class

The Sulfates are an important mineral class and include some very interesting and attractive specimens. Although many minerals belong to this class, only barite, gypsum, and anhydrite can be considered common. The basic chemical unit is the (AO4) complex anion with a charge of negative two (-2).The sulfites

Mineral Gallery - the Oxides Class

In a strict sense, minerals that belong to the more complex mineral classes such as the silicates are really oxides. But this would be cumbersome for mineralogists to be able to deal with only the four different classes of the elements class , the halides class , the sulfides class and finally the extremely large oxides class

The Sulfides - Rocks And Minerals 4 U

The Sulfides. The sulfides are made up of sulfur combined with another mineral, usually a metal. Many of the world’s primary metal ores belong to this group. The chart below lists some of these metal ores and the metal that is produced from them. Cinnabar - This bright red mineral crystallizes around hot springs or hydrothermal veins.

Sulfide mineral - Wikipedia

The sulfide minerals are a class of minerals containing sulfide (S 2−) or disulfide (S 2 2−) as the major anion.Some sulfide minerals are economically important as metal ores.The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts. Sulfide minerals are inorganic compounds

Mineral - Sulfides | Britannica

Mineral - Mineral - Sulfides: This important class includes most of the ore minerals. The similar but rarer sulfarsenides are grouped here as well. Sulfide minerals consist of one or more metals combined with sulfur; sulfarsenides contain arsenic replacing some of the sulfur. Sulfides are generally opaque and exhibit distinguishing colours and streaks. (Streak is the colour of a mineral’s ...

Reading: Classes of Minerals | Geology

Reading: Classes of Minerals. Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–.

Mineral - Classification of minerals | Britannica

Mineral - 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). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...
