Tiberium refinery (Tiberian Sun)

The second-generation Tiberium refinery, used by GDI, Nod and CABAL during the Second Tiberium War and the Firestorm Crisis, was a facility that refined harvested Tiberium and extracted the raw material from the crystals for processing and later manufacturing of vehicles and weapons for infantry. The process is hazardous to humans, and only qualified workers wearing hazmat suits were permitted in the facility.

Background
Unlike the refineries from the First Tiberium War that used to centrifuge the minerals first, the redesigned successors were forced to melt Tiberium in order to process it further due to the crystals' changes between the two wars.

Refineries continued to be fielded by both armies following the Firestorm Crisis, but returned to centrifuging Tiberium like in the First Tiberium War.

In-game
The Tiberium refinery functions as a drop off point for harvesters, it is one of the basic structures for GDI or Nod to build a battle base. It provides access to build their respective walls, gates, Tiberium silos, defenses (component tower for GDI and laser turret for Nod), war factories, radar stations and pavement. The structure is large, but fragile. When it is destroyed, it will leave Tiberium behind.

Trivia

 * Certain animations were disabled for unknown reasons. For instance, when a harvester detaches its container, it was supposed to be seen entering the refinery instead of simply popping on and off the harvester.
