Nickel Laterites: The World's Largest Source 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% and 1.2-1.7% respectively. How do they form?

Limonite type laterites (or oxide type) are highly enriched in iron due to very strong leaching of magnesium and silica.

Silicate type (or saprolite type) nickel ore formed beneath the limonite zone.
