Laterite Wikipedia

Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rustyred coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which produces

Lateritic nickel ore deposits Wikipedia

Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.
