You can't. For Mage Wand and Elemental Wand, you can only cast the spell once per round b/c it is spellbound. Schwenkgott's post is correct about that. Other wands like [mwcard=DNQ09]Wand of Healing[/mwcard] and [mwcard=MWSTX1CKQ05]Dispel Wand[/mwcard] state on them that they can only be cast once a round.
For weapons, they do not get used as a quick spell, so you can't attack with them with your QC marker, even if they are a quick action. The only way to attack with them twice in the same round is, as lettucemode says, with Battle Fury, the double or triplestrike trait, or with guarding.
