10/10/2017 Therefore, all minerals except silicate minerals are categorized as nonsilicate minerals. These minerals have a wide range of applications in industrial productions, constructions, etc. Difference Between Silicate and Nonsilicate Minerals Definition. Silicate Minerals: Silicate minerals are minerals composed of silicate groups.
Silicates are the most widespread of the minerals. They are made up of oxygen and silicon the number one and number two most abundant elements in the earth's crust. By themselves they make up over 90% of the weight of the earth’s crust. Most rocks are composed mainly of this class of minerals.
6. Oxide Minerals: Next to silicate minerals, oxides occupy an important position in the list of rock forming minerals. Some of them are important as non-metallic refractory minerals (e.g. quartz, corundum, spinel and rutile). Many others are very important as source (ore) minerals of metals such as hematite, magnetite (iron), cuprite (copper ...
Non-Silicate Minerals. Minerals can be classified as either silicate - that is, containing silicon and oxygen - or non-silicate - that is, lacking silicon. While most of the earth's crust is ...

A silicate mineral (or silicate for short) is a mineral containing silicate structures; so silicate minerals can be classified according to their silicate structures as lattice silicates, sheet silicates, chain silicates, and so forth.
Silicate minerals are those with more atomic percent silicon oxide than other constituent elements. For example, kaolinite is Al 2 Si 2 O 5 (OH) 4.If aluminum (Al) at two atoms per molecular unit were the most numerous element, kaolinite would be an aluminide.. As the most numerous element is oxygen at 9 for 52.9 at %, kaolin is an oxide.
The Mica Group is the name given to a group of silicate minerals that have silicon and oxygen as their two major components. Muscovite is a member of the mica mineral group. It is more important as a rock-forming mineral than as a collectible specimen. Olivine is a group of minerals that come from magma. It is important as a rock-forming mineral.
