The term for a mineral that contains a valuable metallic element is called an "ore." Ores are mined for the extraction of the metal, which can then be processed and refined for various uses. The economic value of an ore is determined by the concentration of the desired metal it contains and the cost of extraction.
An example of a mineral that contains more than one element is feldspar, which is a group of rock-forming tectosilicate minerals. Feldspar typically contains a combination of elements such as aluminum, silicon, oxygen, potassium, calcium, and sodium in varying proportions.
The mineral that fits the description provided is hematite. This mineral has a metallic luster, silver color, black streak, and contains iron. Hematite is commonly used as an iron ore and displays these characteristic properties.
Actually, a mineral is an ore if it contains another mineral. It can also be sold for a profit, once the USEFUL mineral is either melted out, or drilled out. Then the left over of the ore is useless, but the mineral itself can be sold for profit purposes.
Halite.
Aluminium is an element and contains no minerals. It is, however, obtained from bauxite.
If a mineral contains more than one element it is called a
A silicate is a mineral which contains the element silica.
For example graphite.

A mineral may consist of a single element, but most often contains two or more elements. Gold--single element mineral. Calcite--made up of calcium, carbon and oxygen.

A mineral that contains a useful amount of a particular element is an ore. An ore containing iron is called iron ore, such as magnetite (Fe3O4), and hematite (Fe2O3), which contain 70% iron.https://en.wikipedia.org/wiki/Iron_ore
