Most metals are found in nature in a combined state, owing to their high reactivity. Metals found in a combined state in the earth's crust are known as minerals. Only those minerals that have a relatively high concentration of metal and can be extracted in an easy and cost-effective process are called ores.
The only metals found in free (or) native state are gold and platinum. They are usually found along with earthly (or) rocky impurities such as sand and clay in the earth's crust.
The relative abundance of metals varies in the earth's crust.
