The reason eathbenders can't metalbend platinum is that it is pure and totally refined metal. Metal commonly used for metalbending, as shown above, contains tons (relatively) of earth in it, an thus the earthbenders can use that as a base for their bending. Platinum is so pure that it has next to no earth in it, so it is impossible for metalbenders to find trace earth and make that connection to bend it. It is similar to how waterbenders can bend a wooden tree which is alive, and has water in it, but not a wooden desk, which is dead, and has next to no water in it.
