Coppersmith extensive degree it must be annealed. This process involves heating the metal and then rapidly cooling it in water. The cooling stage is known as quenching. By heating the copper, the molecules in the metal are relaxed, and thus able to align themselves in a more uniform fashion. This allows for easier shaping of the metal. In order to keep this uniformity within the metal, it is cooled instantly. This prevents the molecules from moving around and causing tension in the structure of the metal. Unlike ferrous metals—which must be cooled slowly to anneal—copper can be cooled slowly in air
Radioactive scrap metal furnace. This is heated to form molten aluminium. From the furnace three main streams are obtained, metal product, dross (metal oxides and halides which are skimmed off the molten metal product) and off gases which go to the baghouse. The cooled waste gasses are then allowed out into the environment. It is normal that good-quality scrap copper, such as that from a nuclear plant, is refined in one furnace before being refined further in an electrochemical process. The furnace generates impure metal, slag, dust and gases. The dust accumulates in a bag house, while the gases are vented to the
