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 …
• A breakthrough process: Treats both limonite and saprolite in same flow sheet • IP protection strategy to ensure exclusivity: The DNi Process is an atmospheric hydrometallurgi cal process developed to treat the full laterite profile (from limonitic to saprolitic ores) and is be lieved to be the only pr ocess capable of doing so economically. 1.
Inco (2002) proposes to adopt an innovative PAL process for the nickel laterite operations at New Caledonia. After solvent extraction nickel oxide will be produced by pyrohydrolysis and this material may easily be converted to utility nickel for the Asian steel industry.

In contrast, the laterites cannot be significantly upgraded; a tonne of ore is a tonne of feed to the extraction process. Further, the only significant by-product in a nickel laterite is cobalt, and this is recovered in very few plants. Thus the laterites are disadvantaged in both costs and revenues.
A review has been completed of current and proposed processing technologies for nickel laterite ores. Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore

Overall, the modelling of the electric furnace smelting of nickel laterite calcines has provided useful insights into the nature of the process, especially the way in which the Fe/Ni ratio of laterite and the target nickel grade of the ferronickel affect process performance.
reagent was developed to fit into a QNI-developed nickel recovery process based on a modified Caron process. While operating, Cawse Nickel Operations used a flowsheet originally conceived by BASF and further developed by Cawse, for the recovery of nickel from laterite ores using High Pressure Acid Leaching (HPAL).

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.

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 rusty-red 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 ...
