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–.

Chemical composition: Ore minerals typically have a specific chemical composition that distinguishes them from other minerals. They often contain high concentrations of valuable elements or minerals that are …
All mineral species of a certain class are therefore chemically similar because they possess the same main anion group. Mineral classes may then be further subdivided according to physical features, which cations are …
The ore occurrence with mining value is called mineral deposit, which is the product of mineral accumulation to a certain extent scattered in nature. For example, the average content of iron in the earth's crust is about 5%, and the lowest mining grade of iron ore is 25%, which indicates that iron must be enriched more than five times to ...
