Q. Show the Purification of Metals?
The metals obtained by metallurgical processes still have some impurities which persist from the ore or are derived from the flux or the fuel used. In order to get pure metal, further purification or refining is required.

Some refining processes are designed to recover valuable metal impurities also, such as, silver, gold and platinum.
