Scorpion812 Posted June 22, 2017 Share Posted June 22, 2017 Hi, I wanted to know if it is possible to do this, I know that it is insoluble in water but is it possible to somehow decompose it into Pure Magnesium and CO2?I saw this:https://www.google.com/patents/US5279716MgCO3 →MgO+CO2 (3) If anyone knows how to, please reply Link to comment Share on other sites More sharing options...
taiwanluthiers Posted June 22, 2017 Share Posted June 22, 2017 https://en.wikipedia.org/wiki/Pidgeon_process I hope this helps... It would be easier to buy the stuff. Link to comment Share on other sites More sharing options...
Scorpion812 Posted June 25, 2017 Author Share Posted June 25, 2017 thanks, I think that there isnt an example with magnesium carbonate on that page, but i will take a further look. I know that its cheaper to buy, but i just wonder if its possible Link to comment Share on other sites More sharing options...
Arthur Posted June 25, 2017 Share Posted June 25, 2017 There must be a process to extract magnesium from it's ores, BUT which ore and by what reaction. http://www.corrosion-doctors.org/Electrowinning/Sodium.htm might offer some clues for a chemist, and the 600C offers lots of fear for your Mother/wife/insurers, Oh! then there is the chlorine gas as well.

Arthur Posted June 25, 2017 Share Posted June 25, 2017 Probably a look for the alloy of "alloy wheels" may show something useful. Maybe look at scrap from the auto industry. Link to comment Share on other sites More sharing options...

Magnesium oxide is not Mg metalic... Link to comment Share on other sites More sharing options...
Arthur Posted July 13, 2017 Share Posted July 13, 2017 Magnesium Oxide is also a very stable refractory material good to about 3000K -not a good place to get stuck. Mg Carbonate to Mg chloride may be more useful. Also a trip to a scrap yard for Mag alloy wheels -even bent ones! would be a cheap and easy solution.
