Bobs/Angel's ore Refining for beginners : r/factorio

You need 3 crushed saph to make 2 iron plates. So here, you have a net 4 saph ore (needs 2 to crush) to 2 iron plate ratio. Adding sorting turns into this: 2 ore - crush = 2 crushed ore. 4 crushed ore - sort = 2 iron ore, 1 copper ore. Smelting non-crushed ore is a 1:1 ratio, so you get 2 iron plates and 1 copper plate out of this.
