Most laterite ore deposits are made up of both limonite (iron rich) and saprolite layers, with the thickness of each layer varying significantly across different deposits. Limonite, which accounts for nearly double the amount of saprolite available globally, is more amenable to processing via hydometallurgical techniques, while saprolites are

Nickel laterite ore is classified into two principal ore types: saprolite (silicate ore) and limonite (oxide ore). Saprolite-type ore characterized by high magnesia and silica contents is treated by pyrometallurgy process. On the other hand, limonite-type ore is subjected to hydrometallurgy process to produce nickel products. Hydrometallurgy process requires that a raw material to meet the

Saprolite (from Greek σαπρος = putrid + λιθος = rock) is a chemically weathered rock (literally, it means "rotten rock"). More intense weathering results in a continuous transition from saprolite to laterite.. Saprolites form in the lower zones of soil horizons and represent deep weathering of the bedrock surface. In lateritic regoliths – regoliths are the loose layer of rocks

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? Many factors affect the formation of nickel laterites, including the original rock the soil develops from, the climate, the rate in which weathering occurs, drainage of groundwater and the tectonic setting.
