Executive Summary

Russian Copper Smelter
Russian Copper Smelter

Russian Copper Company has modernized its Karabash smelter in the Chelyabinsk region of Russia's Ural Mountains. An Ausmelt smelting and rotary holding furnace replaced three old shaft furnaces. The new smelting system processes approximately 460,000 tonnes/year of concentrates, producing matte for subsequent conversion to blister copper in existing Peirce-Smith converters.

Ausmelt successfully completed this project with a CENTUM CS 3000 production control system from Yokogawa Australia.

Ausmelt Limited was awarded a PACE Zenith Highly Commended Award in 2008 for the technical excellence and innovation incorporated in the plant. The Karabash smelter has also won two prestigious awards from the Russian government for environmental and ecological excellence.

The Challenges and the Solutions

The project required Ausmelt to provide metallurgical and operational support to the end user, which was difficult due to the distance between Ausmelt's office in Melbourne, Australia and the Ural Mountains in Russia. The solution was a remote connection via Microsoft Terminal Services across the Internet, which enables an Ausmelt technical expert in Melbourne to log on to the Yokogawa control system at the Karabash smelter and perform investigative, consultative, diagnostic, and corrective services.

The Ausmelt top submerged lance technology optimizes critical processes such as feed material dissolution, energy transfer, reaction, and primary combustion, which all take place in the slag layer in the smelter vessel. The intense agitation in the vessel caused by submerged gas injection ensures that reactions occur rapidly and residence times are low. The degree of oxidation and reduction is controlled by adjusting the fuel to oxygen ratio supply to the lance, and the proportion of reductant coal to feed. This enables the furnace to be operated at strongly oxidizing through to strongly reducing conditions. Operating temperatures range from 900°C to 1400°C. Yokogawa's highly reliable CS 3000 production control system brings high availability to the plant operation.
