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 production
Primary nickel is produced and used in the form of ferro-nickel, nickel oxides and other chemicals, and as more or less pure nickel metal Nickel is also readily recycled from many of its applications, and large tonnages of secondary or "scrap" nickel are used to supplement newly mined metal
