Codelco, the world's largest copper producer, and Finnish metals and technology group, Outokumpu, have agreed to jointly develop and implement a new copper flash smelting
application at Codelco's Chuquicamata smelter in Chile.
Ltd over contractual obligations in the Outotec Flash Smelting
and Flash Converting license
The agreement covers Outotec Flash Smelting
licence, the supply of proprietary process equipment and services for Zijin's copper smelter project in Shanghang in Fujian Province.
One project that has already been given the green light is the investment of around $25M in the reconstruction of flash smelting
furnaces at the Norilsk Mining Co's Nadezhdensk metallurgical works.
The smelting and converting equipment is being replaced by Outokumpu flash smelting
and Kennecott Outokumpu flash converting technology.
Outotec will supply the latest flash smelting
technology improvements to the upgrade of Rio Tinto's Kennecott Utah Copper smelter in the U.
on the modernisation of KGHM's HM Glogow II copper flash smelting
furnace in Poland.
The additional smelting is accomplished with a system comprising: two parallel, steam-operated concentrate drying lines and dry concentrate pneumatically conveyed to the loss-in-weight system (for even flow to the concentrate burner); flash smelting
furnace; waste-heat boiler; electrostatic precipitator; gas quenching; and the Boliden Contech Hg removal system--developed jointly with Norzink--to assure high-quality acid product.
