Australian researchers at Swinburn University of Technology have developed a process for producing iron on Mars, suggesting that concentrated sunlight be used as an energy source and that iron be extracted from regolith through carbotermic recovery.
Experiments on the Perseverance Mars were shown to be capable of extracting oxygen from the Red Planet by electrolysis of carbon dioxide.
In their calculations, scientists have shown that the hot gas produced by the electrolysis of carbon dioxide will be rich in CO. It can be used for preheating regolithics.
Researchers have analysed the composition of Martian regolithics with 99.9% conversion, and the alloy will contain a small amount of carbon, silicon, phosphorus and chrome.
The authors believe that the material obtained could be used for the independent production of various machines and devices for the Mars colony. Technology is based solely on local materials and does not require the delivery of cargo from Earth.
If you want to build something big on Mars without having to pay for launching everything from Earth, it could be a very valuable process.
