Nickel Laterite's Integral Role in the Coming Nickel Boom
This future onslaught of demand will be fulfilled by nickel laterites, which, today, have a minimal role in the Class 1 nickel market. In my opinion, the drop in nickel sulphide production, exploration and development over the coming years will force battery makers to consume nickel produced from the HPAL processing of laterite ores.

Nickel Laterites: The World’s Largest Source of Nickel
Although nickel Laterites make up 70% of the world’s nickel reserves, few of them become producing mines. Over the last 60 years magmatic sulfide nickel deposits produced 60% of the world’s nickel. In the last 10 years, the production of nickel from magmatic sulfide deposits has slowly decreased and begun to plateau.

Pelletizing Aids in Upgrading Low-Grade Nickel Laterites
In the case of nickel laterites, the ore is typically crushed and ground, then mixed with the chosen reductant and any other additives, and pelletized into pellets in the range of 10-15mm. As with other metallurgical applications, pelletizing may be carried out using either a rotary drum (balling drum) or disc pelletizer (balling disc).

Laterite
Silicate type (or saprolite type) nickel ore formed beneath the limonite zone. It contains generally 1.5-2.5% nickel and consists largely of Mg-depleted serpentine in which nickel is incorporated. In pockets and fissures of the serpentinite rock green garnierite can be present in minor quantities, but with high nickel contents
Nickel laterites are thick weathering profiles derived by leaching of ultramafic rocks by meteoric water. Olivine or derived serpentine provides the nickel. Profiles with economically significant deposits derive their Ni from 40-m (15−100 m, 10 th −90 th percentile range) thicknesses of protolith grading 0.16 to 0.3 percent Ni and 5.5 to 10

Nickel-Bearing Laterite Deposits in Accretionary Context
In the rest of the profile, Ni is mainly hosted by iron oxy-hydroxides (dominant goethite, subordinate hematite) in the typical low-grade oxide ore type. Nickel content is correlated with goethite crystallinity and anti-correlated with hematite proportion. Nickel content thus decreases, while hematite increases upward (Dublet et al., 2015, 2012).

1. Introduction. Nickel natural resources mainly occur as two types of sulfidic and lateritic (oxidic) ores. Despite the large share of the world lateritic nickel resources (about 70%), nickel is mostly extracted from sulfides (Dalvi et al., 2004).The reason is that nickel in sulfidic ores is aggregated as particular minerals such as pentlandite, while nickel in laterites is usually dispersed
