Nickel processing - Extraction and refining | Britannica

Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purifi ion; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel appli ions, 75% pure nickel can be used without further purifi ion, depending on the composition of the impurities.
