Ore Wikipedia
Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.. The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost
