Is coal dust a mineral

Coal dust is not considered a mineral.

Here’s why:

Minerals are naturally occurring, inorganic solids with a specific chemical composition and crystalline structure.

Coal, on the other hand, is an organic material formed from the remains of ancient plants. It does not have a consistent chemical formula or crystalline structure, so it doesn't meet the strict definition of a mineral.

Coal dust is just fine particles of coal — so it's still organic, and still not a mineral.

However, coal dust can contain trace amounts of minerals, especially if mixed with other rock or impurities from the mining process. But as a whole, it’s not classified as a mineral.
