ELI5:What happen if i put a rock in a soda can and put in in the recycle bin? In other word, how do they filter stuff when i'ts being recycle?

Well, once the paint is removed. The metel is melted down and the rock with it. Then it put into a mold. While it cools the rock (melted) floats to the top as it is less dense. Now fully hardened (~ladies) the melted rock (on top) is broked off. Now you have a mostly pure thing of metel now can be remelted and shaped to make you another can.
