Nickel Laterites: The World's Largest Source of Nickel
The clay zone is rich in calcium, sodium, magnesium, iron and aluminum also known as smectites which can contain trace amounts of nickel. The nickel in the limonite zone is found within the iron oxides such as goethite and hematite. The saprolite and limonite zones tend to contain the higher grades of Ni and can range from 1.5-3% …

Rapid dehydroxylation of nickeliferous goethite in lateritic nickel ore
A method for extracting Ni and other metals from lateritic ores by means of shock heating has been investigated. Shock heating releases some of the metal from its goethitic host. Even though the transformation of pure goethite to hematite is known to occur via intermediate hydroxylated phases, the effect of other metals such as Ni …

LATERITIC DEPOSITS
Preamble. Nickel-cobalt lateritic deposits are residual concentrations formed by tropical-style weathering of ultramafic rocks. Lateritic deposits include a number of deposit sub-types that result from different geological, geomorphological and climatic conditions. Typically, a profile is developed with different zones.
