Nickel Chemistry

nickel deposits in the world. Extraction of Nickel In 1899 Ludwig Mond developed a process for extracting and purifying nickel. The socalled Mond Process involves the conversion of nickel oxides to pure nickel metal. The oxide is obtained from nickel ores by a series of treatments including concentration, roasting and smelting of the minerals.
