Smelter

While not the most immediate concern when landing on Mars, a smelting device housed within a large building able to process a large variety of ore into metal is incredibly useful for sustained existence on the planet. Ad Astra Development Zone features several hundred of these smelter modules outputting hundreds of tons of ingots per day using ore dug up from the Martian Regolith.

The Duskworks's smelters are a faithful recreation of the original smelters used on the Ad Astra Development Zone, albeit with some tweaks and changes to their efficiency. Including greater handling of byproduct and speed increases.

Red Planet smelting processes are a bit more complex than smelting back on Earth. In one example, smelting steel back on Earth involves the usage of coke to supplement the carbon needed to fabricate steel. On Mars however, large expeditionary mining and searching has never located any tracts of coal. Therefore, in order to create steel, massive distillers grab carbon dioxide out of the air and bring it within the smelter where it undergoes an electrolysis reaction to split the CO2 into carbon and oxygen.

"Electrolysis of carbonates in anhydrous environment can produce either $CO+O2$ or $C+O2$depending on conditions. A base, remaining in electrolyzed liquid then can capture carbon dioxide from other sources and be recirculated.
