The only thing related to 'reclaiming a queen' in Chess is the promotion
of a pawn to a queen. For this to happen, the pawn must reach the final
row of the board, from its owner's perspective - in other words, get your
pawn all the way to the other side of the board, and you can promote it to
a queen.
(Additionally, the term 'reclaiming' is a bit inaccurate here, because
it is possible to get more than one queen by doing this multiple times.)
