Ore - Wikipedia
An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining ; they are then refined (often via smelting ) to extract the valuable element, or elements.
