Tungsten element extraction method – surface mining technique

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. Therefore, tungsten is extracted chemically from the crushed ore in a series of chemical reactions, titrations, washings, and filterings.
