Captured carbon dioxide converts into oxalic acid to process rare earth elements - C2V - CO2 to Value In fact - CLIMAX
A team from Michigan Technological University has designed a carbon dioxide scrubber. They are working on converting the carbon dioxide that they capture into oxalic acid
Oxalic acid is a naturally occurring chemical in many foods. In industry, oxalic acid is used to leach rare earth elements from ore bodies. The rare earths are in turn used in electronics such as cell phones.
Rare earths are not presently in many countries, with China producing 90 percent or more of the rare earths in the world. By producing oxalic acid domestically, it may be possible to profitably extract rare earth elements in other countries, leading to higher self-reliance.
