Coal carbon is valuable part or mineral that helps make up the human body.

Find me one scientist who will agree the body is composed of free carbon. It's impossible.

Question:
Why is coal not classified as a mineral?

Answer:
Minerals are naturally-formed substances that have a specific chemical makeup. They are created when elements combine. Minerals are non-organic and most have a set crystalline structure. Examples of minerals include diamond, azurite, beryl, and pyrite.
