	Smelting converts a metal oxide ore to the metal. The output is typically a standard-sized metal bar. It requires substantial thermal [[energy]], and often some chemical input such as [[carbon monoxide]] (made from [[charcoal]] or [[coke]] on [[Earth]], but coke is not readily produced on [[Mars]]) or [[hydrogen]]. Mars has abundant [[iron]] oxides and even more [[aluminum]] oxides, and it's possible (though by no means certain) that good quality ores of other metals (e.g. copper oxide) may be found. The problem is not the oxide itself, but its dilution in other minerals. What is needed are areas where the oxides are concentrated. Considerable ~~separation of~~ the desired ore from other Martian regolith constituents will generally be required before it is suitable as smelter input.
