			Interesting addition. Might it be possible to add links to processes that might be used to extract useful ores for in situ production from these minerals?

	To get the iron from hematite it is usually smelted with carbon. The iron-oxygen bond is strong in hematite so a stronger bond must be presented to remove the oxygen. The trick is to mix the ore with powdered coke, then smelt them while keeping the oxygen infusion low enough that you have a 1 to 1 mol ratio of carbon and oxygen. This produces CO, which then strips an additional oxygen atom from any iron ores present. The result is CO<sub>2</sub> and reduced ore. Continue reducing until you have iron and CO<sub>2</sub>. It's the tried and true method of ancient iron production. Nowadays we call it fancy names like "carbothermal reduction." - [[User:Jarogers2001\|Jarogers2001]] 00:55, 19 November 2008 (UTC)		To get the iron from hematite it is usually smelted with carbon.

	:From the atmosphere? I really have no idea for carbon black (coke substitute). If it were me, I would skip the carbon/coke step entirely and go straight to CO. This can can be accomplished by burning methane in an oxygen starved environment. Methane can be obtained from the martian atmosphere via a sebatier reaction. It is much less low tech, but you'd have to use high tech to get back to low tech anyways so I see little point unless coke/carbon can be obtained as a byproduct of some other activity. It would be easier to just circulate heated CO/CO<sub>2</sub> upwards through a column while poring ore into the top (as in a blast furnace), but you'll need a lot of power for that. - [[User:Jarogers2001\|Jarogers2001]] 07:00, 24 November 2008 (UTC)		:From the atmosphere?
