Refining Various Methods Vedantu
The extracted impure metal is called crude metal. Refining of metals is the final process. After the extraction process the metal is free from impurities. The refining method to be chosen will depend on the physical and chemical properties of a particular metal. There are different methods of making a metal pure : Distillation.

Zone Refining: Learn its Principle, Process, Limitation & Uses
Zone refining is a method used to purify a substance, typically a metal, by selectively melting and solidifying small regions of the material. The process involves passing a small heater back and forth along the length of a thin rod or wire of the substance being purified. This creates a "zone" of molten material that is surrounded by solidRefining of zirconium silisbme processManufacturer Of refining of zirconium silisbme process A process is given for the electrolytic refining of an alloy of titanium or zirconium 14-Dec-2021 690 COMrefining of zirconium silisbme process
