Aluminum, Oxygen, And anything else that is not Silicon.
Graphite is a nonsilicate mineral composed primarily of carbon. It does not contain silicate minerals in its chemical composition.

Bauxite is nonsilicate because it does not contain a mixture of oxygen and silicon.
It is a silicate. For sure.
There is no difference. The calcium in milk is the same calcium found in rock minerals, the iron in your car is the same as found in your corn flakes.
Calcite is a common nonsilicate mineral found in rocks, including limestone and marble. Hematite is another nonsilicate mineral that occurs in rocks, often as a major component in iron ore deposits. Halite, also known as rock salt, is a nonsilicate mineral that is frequently found in sedimentary rocks such as evaporites.
One example of a nonsilicate mineral that cleaves when it breaks is calcite. Calcite, composed primarily of calcium carbonate (CaCO3), exhibits perfect cleavage in three directions, producing rhombohedral fragments. This property makes it distinctive among nonsilicate minerals. Other nonsilicate minerals also exhibit cleavage, but calcite is one of the most well-known examples.
