Can ions pass tought a conductive wire like electrons do ?
Not in conventional wires, at least not in a significant amount. Wires are solid, therefore the ions are bound in specific locations. If you melt the wire, ions can move.
There are unconventional "wires" that do conduct ions, however: http://en.wikipedia.org/wiki/Salt_bridge
Ions ARE the [charged] current carrying particles in electrolytes, like batteries and seawater. Neither electrons in conductors nor electrons nor holes in semiconductors are considered ions.
