After the mineral has been identified and proven to be a mineral, it is classified as a silicate or non-silicate mineral, based on its composition. Silicate Minerals The most commonly found group of minerals in the Earth's crust is the silicate group. Almost all silicate minerals have silicon and oxygen as their base units.

Silicate minerals such as clays and feldspars in sandstone pores are normally removed using mixtures of HF and HCl, whereas carbonate minerals are usually attacked with HCl. The chemical reactions are summarized in Table 16.1.The amount of acid required to dissolve a given amount of mineral is determined by the stoichiometry of the chemical reaction.

The chemical name for the substance of quartz is silica; and any mineral that is composed in part of silica is a silicate. In the Classification of Silicate Minerals and the study of minerals and rocks, silica is called an acid; in silicates, the substances other than silica are called bases, for example, lime, potash, and soda. When giving the full name of a silicate the names of these bases ...

Orthosilicates. Orthosilicates are minerals consisting of only single SiO 4 4-units. The cations are some other metals. For example, the following minerals are orthosilicates: The Be and Zn ions are tetrahedrally bonded to the oxygen of the silicate in these two minerals: phenacite, Be 2 SiO 4 and willemite, Zn 2 SiO 4.In olivine, (Fe, Mg) 2 SiO 4, the cations are either Fe 2+ or Mg 2+.

Basically, silicate minerals show six different structural styles: Isolated tetrahedra are separated by positively charged metal ions all around. This is for example the structure of the mineral olivine.; Tetrahedra form rings that are linked together by positively charged metal ions. This structure is for example found in the mineral tourmaline.
