Nickel processing | Extraction & Refining Techniques | Britannica

nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high melting point of 1,453 °C (2,647 °F) and a ...

Selective Reduction of Laterite Nickel Ore

nickel ore is the highest dehydroxylation process compared to other lateritic nickel ore types. It occurs at temperatures of 261­270°C, while the removal of the hydroxyl group in the limonite nickel ore occurs at a temperature of 400­600°C.12) The removal of hydroxyl groups in chlorite (Fe,Mg,Al) 3-(Si,Al) 2O 5(OH) 4 starts at 602°C and ...

Nevertheless, when reduction roasting–magnetic separation is used to treat laterite nickel ore with low nickel content, increasing the dosage by approximately 8–20% inevitably reduces equipment life and increases cost (Liu et al.,2021). Therefore, improving the grades and recoveries of iron and nickel is of major significance.
