Outotec to supply technology for upgrading Cu smelter in Utah
Outotec Oyj (Espoo, Finland; www.outotec.com) will supply the latest flash-smelting technology improvements to the upgrade of Rio Tinto's Kennecott Utah copper smelter in the U.S. The contract value is approximately €14 million and will be booked in Outotec's third quarter order intake.
Kennecott has operated the Utah copper smelter since 1995 utilizing a combination of Outotec Flash Smelting technology and Kennecott-Outotec Flash Converting technology, which has been jointly developed by the two companies. Outotec's scope of work includes equipment deliveries such as proprietary feeding system, concentrate burner, process control, furnace cooling and anode casting upgrade.
Once completed the upgraded flash furnace will ensure highly efficient production combined with a long campaign life. Flash Smelting combined with Flash Converting is the world's cleanest technology for primary copper smelting. Since it makes use of the reaction heat of the feed, copper sulfide concentrate, minimum amount of external fuel is needed in the process. Owing to low volume of process gas and compact and sealed equipment, sulfur capture exceeds 99.9%. Thanks to its environmental performance the Kennecott Utah Copper smelter has been the world's benchmark smelter and the upgrade will further improve its position.
