Laterite
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. …
Laterite - an overview | ScienceDirect Topics
The Bitincke nickel laterite deposit is located in the southeast of Albania. The nickel silicate and iron–nickel are mainly located in Devoll (Bilisht and Bitincke), Pogradec (Guri Kuq and Cervenaka), Librazhd (Prrenjas, Skroskȅ, Xixillas, and Bushtrice), Kukes (Mamez, Trull Surroi, and Nome), and many more (Fig. 8.2).

And about 65% of the world nickel reserves stored in nickel oxide ore deposit in, due to its due to the presence of the sake of iron oxide were red, so also known as laterite. The laterite nickel ore in the discovery of multiple distribution along the south, north of the Tropic of cancer, such as Australia, Papua New Guinea, New Caledonia, Indonesia, the Philippines, Cuba and other places.
Nickel processing | Britannica
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.
Top 5 Nickel Miners To Consider Before The Nickel Boom ...
Mar 28, 2018 · Nickle laterite ores are easier to find near surface, however the nickel is harder and more expensive to extract. Nickel laterite miners are generally higher cost …
Nickel processing - Extraction and refining | Britannica
From laterite ores. Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore.
The nickel laterite challenge - Australian Mining
Jun 21, 2012 · Nickel occurs in essentially two ore types; magmatic sulphides and (wet or dry) laterites. The sulphides typically are found hundreds of metres below ground with principle mineralisation including pentlandite (Ni, Fe)9S8. Major deposits such as those in Canada and Russia have historically provided the bulk of nickel production.

Nickel Laterites Integral Role in the Coming Nickel Boom ...
Nickel laterite ore processing depends on the zone from which the ore is mined. As outlined earlier, each zone within a laterite deposit is very different in its stone composition and, therefore, restricts the processing technique that can be used to extract the nickel.

The segregation process as applied to nickel laterite ores involves the formation of gaseous nickel and iron chlorides which are subsequently reduced to form ferronickel on the surface of a solid carbon reductant. A fundamental study of the process has been carried out …
Laterite | Cobalt Institute
Laterite In tropical and subtropical climates intense weathering of ultramafic rocks may cause significant cobalt and nickel enrichment in surficial residual deposits known as laterites. Cobalt dispersed in silicates and sulphides within the host rock is remobilised and deposited in weathered layers as hydroxides and oxides near the surface and as silicate at deeper levels.
