Precious Metals Refinery, Ust-Kamenogorsk Metallurgical Complex
Melting of precious metals bearing feed with Zn distillation and further condensation, cuppelation to produce Au-Ag alloy, electrolytic Ag refining and bars melting.
Production output per year:
- Batteries made of silver compounds have high energy density and massive energy absorption capacity and are capable of generating heavy current at low inner resistance.
- This precious metal is highly valued as it is used for making commemorative coins.
- Medals with high silver content remain stable when exposed to atmosphere.
- microwave ovens
- Due to its high conductivity and oxidation resistance, silver is used for coating the inner surface of wave guides.
