A typical nickel laterite profile can be divided into four zones (Figure 1). The weathering effect progressively increases from bottom to top with the magnesium content of the ore decreasing and the iron content increasing with increased weathering (Elias, 1981; Burger, 1996). Saprolite. The lowest layer reflects early stages of weathering of ...

Laterite - an overview | ScienceDirect Topics

The laterite is composed of two separate distinct mineralized zones characterized by a nickel silicate zone and a residual iron oxide–nickel phase (Fig. 8.3). The silicate zone contains Ni concentrations reaching up to 1.5 wt.% with lateral and vertical variation. The silicate zone is composed of olivine and serpentine at the base of the horizon and is gradually replaced by secondary ...
