Grinding Mercury or iodine would be a physical change - you are changing the shape but not the element. However, grinding mercury with iodine may be a chemical change if you end up with mercury iodide through a chemical reaction.
Incidentally, I don't recommend actually trying this - mercury is a liquid at room temperature (it is also called quicksilver for this reason) and is very toxic to humans.
