Is there a way to convert Mgo to Mg? Because I found Mgo.
Or is here somebody who knows where i can get Mg.

have you read the rules?

i think not, otherwise you wouldn't have blatently disregarded them. do you know how they make Mg? try doing a little work yourself and find out.

i'm moving this tripe to the watercooler where it belongs....

WATERCOOLER - USE IT!!!

Also yet another newbie who thinks they're too sly to give away their location, but then ask for sources applicable to them, helps if we know what fucking country you're in!

he must think we're run by the government and paid for by his taxes to expect everything handed to him. well actually we're a private organisation and don't just dish answers out. if you want Mg from MgO have a search on google. don't be so fucking lazy.

Question on first post, your future doesnt look good here, but im feeling good and bored so i'm going to toss a coin heads i respond tails i dont either way im sure you'll end up banned.Ah you get heads so i answer but then agian the Mods dont think you deserve one so Goodbye.
EDIT:

Well 3 posts in the time i wrote mine and looked for a coin...

In fact this should work:

MgO + C --> Mg + CO

It needs good heating and possibly an inert atmosphere.

i thought Mg was waaaaay too reactive to do it like that. i was thinking along the lines of Al extraction. melt the oxide and electrolyse it.

True. C + MgO is going to cost shitloads of energy. Furthermore, it could very well be that it won't work because of:

2MgO + 2C ----> Mg2C + CO2

Although I haven't checked if this reaction occurs.

Electrolysis is still the most economical, practical and most safe method.

MgO can be reduced by Al though using high temperatures, but NOT in solution.

Looks like you beat me to it whilst I was buggering about with the big font :)

Best method for converting MgO to Mg woulld be to put some epsom salts into your Big-Fuck-Off-Particle-CANNON, bombard the MgO and then sweep up the Mg atoms into a jam jar.

I shouldn't think always in theory..
Thanks for the correction!

It seems that buying the Mg would be much more easier.

Arn't there already several threads about this? I have studied the problem myself and I know I have talked about it. MgO should be converted to MgCl and electrolyzed in an inert environment, that's how they do it industrially.

infact, would it not be easier to make Mg(NO3)2 and electrolyse that? its melting point is 89*C as opposed to the much higher melting point of MgCl - 714*C. this would seem like the better option to me...

Kingspaz, I think 89C is the melting point of the hydrate, it will simply dehydrate at that temperature IIRC. Furthermore, reducing salts with an oxidizing anion isn't going to work since that will be reduced first. And melting dry Mg(NO3)2 would yield MgO which is impossible to electrolyse because of it's very high melting point.
