Refinery

A place-able structure that uses power to refine various ores to yield their refined resources.

As with all interactive items, you must point the cursor at the refinery and press 'F' to open it's menu: The current power, mass, and power per second for the refinery are at the top of the menu. In the center, you provide the ore that you want refined which, after turning the refinery on, will slowly be refined to (in this case, from Iron ore) Iron fragments.
