I've already worked out most of it, it uses whats already in the game, Commodities and all. Dev team would have to make the code for converting Ore to Refined Item. and making the code for the Smelter. Other than that. they have to pick a Item that the base uses in the Smelting Process. I've only chose one such Item in the whole list.
Most of the rest would have to be worked out by the DEV team, allowing it to convert all Ores or minable goods into it's end Smelting Item. Most of the Items in the game have finished Refined Items.
I was hoping someone else might have more Ideas on this that I have not thought of to help this Idea along.
