Russia's Urals Mining and Metallurgical Company said Thursday it has completed upgrading its Svyatogor copper and zinc ore concentrator at the cost of about $33 million.

The upgrade increases the concentrator's capacity 1.5 times to 2.5 million metric tons of ore a year.

The concentrator has been upgraded in order to enable it to process ore from the Severny copper and zinc ore mine at the Tarnyerskoe deposit, commissioned by UGMK Wednesday.
