What are the different composition of minerals?
Correspondingly, how many different minerals are there?
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.
Also question is, what are the main types of minerals?
The Dana system divides minerals into eight basic classes. The classes are: native elements, silicates, oxides, sulfides, sulfates, halides, carbonates, phosphates, and mineraloids.
Minerals can be found throughout the world in the earth's crust but usually in such small amounts that they not worth extracting. Only with the help of certain geological processes are minerals concentrated into economically viable deposits. Mineral deposits can only be extracted where they are found.
