Environmental Guidelines for Nickel Smelting and Refining
436 Nickel Smelting and Refining cathodes is the most common technology used for nickel refining. Electrowinning, where nickel is removed form solution in cells equipped with inert anodes is the more common refining process used for nickel. Chloride electrolytes are used although sulfuric acid solutions are used more often.

Smelting and refining | Glossary | Sumitomo …
At SMM’s Toyo facilities in Ehime Prefecture, the copper concentrate pre-processing undertaken at Saijo uses pyrometallurgical processes and the nickel refining at the Niihama site uses hydrometallurgical processes entirely. The term "smelting" is used for the extraction of metal from ores using melting and heating (pyrometallurgy).
Nickel processing | Britannica
Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high
Cobalt extraction - Wikipedia
Nickel sulfide concentrates can be treated by either roasting or flash smelting to produce matte from which nickel and cobalt can be recovered hydrometallurgically, or they may be treated by an ammonia solution pressure leach. The residue is removed.

nickel smelting and refining process
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. These processes require their own special precautions. nickel sulfide refining smelting
the refining process to produce iron
Nickel processing Extraction and refining Britannica. In carbonyl refining, carbon monoxide is passed through the matte, yielding nickel and iron carbonyls [Ni(CO) 4 and Fe(CO) 5]. Nickel carbonyl is a very toxic and volatile vapour that, after purification, is decomposed on pure nickel pellets to produce nickel shot. Copper, sulfur, and precious metals remain in the residue and are treated ...
