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

A new method was developed. Nickel and iron was enriched firstly by leaching laterite nickel ore in concentrated alkali solution. In the process, silicon entered to the solution in the form of sodium silie, and nickel and iron were remained in the residue in form of
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.

Adsorption of Metals from MetalOrganic Complexes Derived
Approximately 80% of known nickel and about 95% of cobalt global reserves are found in nickel laterite ore deposits (1, 2, 3) and the rest are in sulfide ores (4). Commercial extraction of nickel and cobalt from laterite ores constitutes one of the most challenging and high cost processing techniques.

Typically this type of Disseminated Ore is seen above and lateral to the higher grade, more massive parts of the system. One of the characteristics of magmatic sulphides is that the individual sulphide grains – like the orebodies as a whole – tend to be zoned having a more copperrich top and nickel rich base.

Laterites are a source of aluminium ore the ore exists largely in clay minerals and the hydroxides, gibbsite, boehmite, and diaspore, which resembles the composition of bauxite. In Northern Ireland they once provided a major source of iron and aluminium ores. Laterite ores also were the early major source of nickel.
NiCo Laterite Deposits of the World—Database and Grade
