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 highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickelExtraction of Nickel Main ore is Pentlandite; Nickel is extracted from ores through the Mond procedure, in which nickel oxides are purified throughout several steps into pure nickel metal It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickelExtraction of Nickel QS Study
