: [[Aluminium]] is a special case in which the [[mineral]] is not [[dissolve]]d in [[water]] but in a [[solvent]] called [[Cryolite]] at very high [[temperature]]s. This is done because the [[mineral]] [[melt]]s at an even higher [[temperature]] than the [[cryolite]] so it is easier to [[dissolve]] it in the [[cryolite]] than to heat the [[mineral]] beyond its [[Melting Point|melting point]].

Used when the [[mineral]] is [[insoluble]] in [[water]] or the [[metal]] [[Chemical Reaction|reacts]] strongly with [[water]].

: The [[electrolysis]] of [[molten]] [[Ionic Compound|ionic compounds]] [[Decompose (Chemistry)|decompose]]s those [[Ionic Compound|ionic compounds]] in a [[liquid]] [[State of Matter|state]].
