Calcined Dolomite, Limestone Powder, Limestone, Iron Ore Lumps, etc.

Minerals are naturally occurring, inorganic solid substances found in the Earth's crust with a definite chemical composition and crystalline structure, whereas ores are specific mineral deposits that contain a high enough concentration of a valuable element (typically a metal) to be extracted profitably.The most critical rule connecting them is: All ores are minerals, but all minerals are not ores. For instance, clay and bauxite both contain aluminium, making them both minerals; however, only bauxite is considered an ore because extracting aluminium from it is economically viable.
