Teknik MetalurgiIntroduction
The term pyrometallurgy in chemical metallurgy refers to the use of high-temperature reactions and processes for the extraction and the refining ofmetalsmetals.
The key parameters in pyrometallurgy are temperature and environment.
Benefits of high temperatures:
• favorable chemical equilibria
• high reaction rates andhigh reaction rates, and
• Possibility producing the metal in molten or gaseous states whichfacilitates its ready separation from other reaction productsfacilitates its ready separation from other reaction products.
Environments: air, reducing gas mixtures, reactive atmospheres containingthe halogens inert gases or even vacuum

the halogens, inert gases or even vacuum.
