Nickel-Bearing Laterite Deposits in Accretionary Context ...

Grades of Ni-laterite deposits (0.8–15 wt% Ni) exceed that of magmatic Ni-sulfide deposits (0.5–5 wt% Ni; Arndt and Ganino, 2012). Cobalt is, in some deposits, enriched in the same proportion, but its initial and final concentrations are roughly 10 times lower. In addition, recent studies about scandium enrichment within Ni-Co laterites of New Caledonia show that Sc-bearing goethites ...

Assessment of the Geotechnical Properties of Lateritic ...

Laterite is a highly weathered material, rich in secondary oxides of iron, aluminum, or both. Geotechnical investigation is one of the effective means of detecting and solving pre, syn and post constructional problems. The geotechnical properties of lateritic soils and their suitability for road construction have been evaluated for selected sites in Minna, North-central Nigeria.
