Earth's crust is composed of many types of rocks (stones) each of which is a combination of minerals 1 or more and in geology; the condition mineral
identifies any naturally occurring solid substance with a specific crystal structure and composition. The mineral's composition refers to the types and
balances of elements making up the minerals. The method these elements are packed collectively determines the structure of the minerals. Many more than
3500 different minerals have been described and there are only twelve common factors (oxygen (O), silicon (Si), aluminum (Al), iron (Fe), calcium (Ca),
magnesium (Mg), sodium (Na), potassium (K), titanium (Ti), hydrogen (H), manganese (Mn), phosphorus (P)) that occur in the crust of the earth. They've
abundances of 0.1 percentages or more than that. Completely other naturally happening elements are found in trace amounts or very minor.
The two types of minerals are as follows:
1. Metallic minerals
2. Non-metallic minerals
The metallic minerals are those from which useful metals (for example. copper, iron) can be extracted for commercial usage. The metals that are considered geo-chemically plentiful occur at crustal abundances of 0.1 percentage or a lot (for example. titanium, manganese, iron, aluminum, magnesium).
The nonmetallic minerals are useful and not for the metals they check, just for their properties as chemical combines. Since they are commonly used in manufacture, they're as well frequently referred to as minerals of industrial. They're classified according to their utilization. A few industrial minerals are practiced as sources of significant chemicals (for example. borax for borates and halite for sodium chloride).
A different important type of minarals (for example. CaCO3, calcite) the sulfides (for example. PbS, galena) and the sulfates (for example. CaSO4, anhydrite). Many of the large quantity minerals in the earth's crust are not of trade measure. In economically valuable minerals (nonmetallic and metallic) that provide the raw substances for industry tend to be hard and rare to determine. Hence, as considerable skill and effort is essential for finding wherever they are extracting and finding them in sufficient measures.
