Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and s at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.
