How do I get my ant farm to produce more queens and how do I collect them?
This can be a very difficult goal to accomplish. Ant colonies need to be very well established before they will begin producing reproductives. Depending on the species, this can take up to a few years. Also, if your ant farm doesn't have its own queen, it can't possibly produce new ants because, with a few exceptions, worker ants cannot produce fertile eggs.
Allowing your colony to grow and providing it with abundant resources is the best way to ensure that it will attain maturity and will eventually be able to produce new queens.
