Tungsten is mostly obtained from the minerals scheelite and wolframite. Tungsten is not refined by smelting or through any other method through which other metals are refined since it has the highest melting point above any other metal. The surface mining methods are used when the tungsten minerals are found in the earth's surface where underground digging is not required.
