The nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent. Mining. With nickel found in two radically different types of ore, it is not surprising that the mining methods differ.

Ferronickel

The feed material for ferronickel production is moist saprolite, a type of laterite. This ore typically contains 1.5%–3% Ni.
