Solved: 19. Impure Nickel, Refined By Smelting Sulfide Ore

Impure nickel, refined by smelting sulfide ores in a blast furnace, can be converted into metal from 99.90% to 99.99% purity by the Mond process. The primary reaction involved in the Mond process is: Ni(s) + 4CO(g) = Ni(CO)(g) Given that the spontaneity of the above reaction is temperature-dependent, without using values, predict the sign of ...

Nickel processing - Extraction and refining | Britannica

Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.

nickel Ore - SlideShare

Jan 28, 2016 · FERRO NICKEL ORE- A recent development in the extraction of nickel laterite ores is a particular grade of tropical deposits, typified by examples at Acoje in the Philippines. This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore.
