Ferrous and Nonferrous Minerals
Iron in the +2 oxidation state is found in ferrous minerals. Iron in the +3 oxidation state is found in ferric minerals. The metals iron and alloys are examples of ferrous metals. Non-ferrous metals and alloys do not have a significant quantity of iron. For instance, copper, aluminium, etc. The following are the differences between ferrous and nonferrous minerals:
Iron makes up most of these minerals.
These minerals don't primarily consist of iron.
They are magnetic minerals.
They are not magnetic minerals.
These minerals are heavier.
These minerals weigh less.
Examples are manganese (Mn), iron (Fe), etc.
Examples are gold (Au), copper (Cu), zinc (Zn), etc.
