The production process for metals in their liquid state is commonly referred to as metal smelting. In smelting, metal ores are heated in a furnace to extract the metal in a molten form. This process often involves the use of a reducing agent, such as carbon, to separate the metal from its ore.
In addition to smelting, the term metal casting can also be relevant when discussing the processing of metals that are poured into molds while in their liquid state to create specific shapes.
