Automatic Sorter/Smelter for Ores

Here is a system I put together of two things. Below, you will find a minecart station that would go down the length of your strip mine. Hitting the buttons will turn each cell into a receive state or a bypass state. Above you will see a sorting system. This will allow you to have your diamonds, lapis, iron, gold, emeralds, and redstone separated and will smelt your iron and gold. See my YouTube vid for more of an explanation. I removed the tower that was in the vid because there are many videos out now with working towers and you can pick the one you want to use. I also added another cell below and compressed the sorting above. Let me know what you think! :)
