RE:RE:The ArcelorMittal PYR link -- yes, there may actually be oneAll iron ore has to eventually be "reduced" -- removing of the oxygen from the initial metal oxide to get to the final metal state -- in order to be turned into steel or iron.
it is a chemical process.
But this happens during the steel making process, not during the pellet making process.
Tradtional or primary steel making uses coal and coke during the smelter phase at high heat to mix with the ore pellets, causing combustion, and forcing out oxygen.
Direct reduction steel making is essentially the same high heat process, but uses hydrogen or natural gas to do the same, instead of coal or coke.
None of these have anything to do with pelletization, and both require pellets that are baked during an induration phase.

just with coke normally but now with hydrogen ?
could reduction be a chemical process ?
