editMetallic ores are usually oxides and require reduction, not oxidation. Biscuittin (talk) 20:51, 2 October 2015 (UTC)
I don't know how best to respond to these things as I'm pretty inept at wikipeding but the page is accurate just incomplete. the vertical can be used most easily for oxidation, more specifically roasting Roasting (metallurgy). other major uses for oxidation in multihearth are combustion of wastes (basically incineration) and activation of carbon. it's hard to do reduction because gas control isn't great, you get some leakage of ambient air which would upset any strongly reducing environment, but you CAN control how much air is in each hearth, in each segment and in that way control where the combustion occurs, where is heat generated etc. alternately they're used with burners to provide heat for roasting and calcining.Wdaloz (talk) 14:25, 31 August 2016 (UTC)
- Yes, the page is really accurate : oxydation is a step step to treat sulphurized ore. Borvan53 (talk) 21:49, 28 November 2016 (UTC)
