Reading this article, one might think that Outokumpu was the only flash smelting technology out there. The INCO flash smelting technology is also currently practiced. Additionally, I'm not sure it's totally correct to cite fluidized bed reactor in the article. It makes it sound like there is two furnaces. And one more thing... the article seems to imply that all copper sulfide ores are processed by flash smelting (in Outokumpu furnaces no less), with a 50/50 split between flash smelter recovery and oxide copper recovery. Are you sure that there are currently no Noranda or other bath-type furnaces, nor any El Teniente, IsaSmelt, or other lance-type reactors operatings? You might want to check that out.BSMet94 (talk) 04:38, 8 May 2009 (UTC)[reply]
Outokumpu says "this process produces 50% of the world’s primary copper"[1].
No. Air (or oxygen enriched air), concentrate, flux, and sometimes additional fuel are dispersed into the inlet chamber of a flash furnace. This is not a fluidized bed. The roasting reactions take place simultaneously with the smelting process.BSMet94 (talk) 20:55, 28 July 2010 (UTC)[reply]
