I don't know if you have a set of tools you can use, but I would use a sifter. You know, those things that have the mesh in the center of a ring of metal. Anyway,to do that, place the mixture in the sifter, and well, sift it. Another tool you could use would be some tweezers, but man, that would take forever:) There are lots of other ways to do this, so if you need more, ask:)
