The raws for my iron ore example would look something like this:

This will take hematite and convert it into "partially processed iron bars". These are bars of metal that are functionally equivalent to iron but are unable to be used to make anything. The second reaction then takes these and changes them into "mostly processed iron bars". The final reaction then takes these "mostly processed iron bars" and converts them into normal, usable, iron bars.
