Nickel processing - Extraction and refining | Britannica
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.
Nickel Metal: Its Properties, History, Production & Uses
The separation process for nickel is highly dependent upon the type of ore. Nickel sulfides, such as those found in the Canadian Shield and Siberia, are generally found deep underground, making them labor-intensive and expensive to extract.

The nickel is removed by washing the organic with water that has been slightly acidified with hydrochloric acid in small mixer-settlers. High concentrations of chloride ions result in the extraction of cobalt from the aqueous phase while low concentrations of chloride ions result in the stripping of cobalt from the organic phase.
