For a substance to be classified as a mineral it must meet the following 5 specific criteria:
1. Natural: A matter is called natural when it originated in nature, that is, without human intervention.
2. Inorganic: A natural matter is called inorganic when it is not of the type that constitutes and characterizes organisms, in other words, when it is not basically constituted by carbon (C) and hydrogen (H) atoms.
3. Solid: A matter is solid when the particles (atoms, molecules or ions) that form it are strongly united occupying fixed positions.
4. Crystalline: A solid matter is called crystalline when its particles are arranged.
5. Defined chemical composition: Minerals have a defined chemical composition.
Therefore, we can conclude that a substance to be classified as a mineral must be a homogeneous solid, formed by natural processes, and generally inorganic. With a defined chemical composition that, sometimes, is not fixed and that presents an ordered atomic arrangement, that is, it has a crystalline structure.
