Rocks are mixtures of minerals. A mineral can be either an element or a compound. A metal ore is a mixture of minerals containing the metal, and other materials in the rock, from which it is economically viable to extract the metal. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal.
