  Nickel laterite is an important mineral source, contributing 40% of world nickel production. Lateritic nickel deposits are formed from the weathering of ultramafic host rock type. Generally formed in the tropical climate to a sub-tropical. Today, most nickel laterite formed in the equatorial region. Countries lateritic nickel producer in the world including New Caledonia, Cuba, Philippines, Indonesia, Columbia and Australia.
The "laterite" term could be interpreted as a sediment rich in iron oxide, silica poor and intensive elements are found in sediments in a tropical climate lapukan (Eggleton, 2001). There also are interpreted as sediment lapukan containing nickel laterite nickel and economical to mine.
Nickel laterite deposit base rock is ultramafic rock; generally harsburgit (Peridotit ortopiroksen rich element), dunite and the types of Peridotit.
