The major environmental impact of refining and smelting is greenhouse gas emissions. These gases result from both the electrical consumption of smelters and the byproducts of processing. The greenhouse gases resulting from primary production include perfluorocarbons (PFC), polycyclic aromatic hydrocarbon (PAH), fluoride, sulfur dioxide (S02), and carbon dioxide (CO2).

exclusive of the smelting and refining processes described above that lead to relatively pure copper. Casting The final recovery process step is the casting of alloyed or refined metal products.
Extraction and refining Roasting and sintering. Both of the main extraction methods for the production of zinc, electrolysis and smelting, require the prior removal of sulfur in a highly exothermic oxidation reaction:. For the electrolytic production of zinc, the roasting of concentrates is achieved in fluidizedbed roasters, in which finely divided and heated particles of concentrate are ...

The smelting and refining of some metals can have special hazards. Examples include nickel carbonyl in nickel refining, fluorides in aluminium smelting, arsenic in copper and lead smelting and refining, and mercury and cyanide exposures during gold refining.
Metal smelting and refining produce gaseous (CO 2, SO 2, NO x, etc.) and particulate matter emissions, sewage waters, and solid wastes. Soil contamination with trace metals is considered a serious problem related to smelting; however, mining and smelting are not main sources of global metal input into soils.
The metals considered included copper, nickel, aluminium, lead, zinc, steel, stainless steel and titanium, by both pyrometallurgical and hydrometallurgical routes in some instances. The environmental profile included greenhouse and acid rain gas emissions, solid waste emissions and gross energy consumption.

The two main processing stages for aluminium production are alumina refining (Bayer process ) and aluminium smelting (Hall–Heroult process ) as shown schematically in Fig. 5. The Hall–Heroult electrolytic process was adopted over a hundred years ago, and is the only process for aluminium production in commercial use today.
