WebNi-Co laterites develop by chemical weathering of ultramafic rocks and supergene enrichment of weathering products mostly under tropical climatic conditions. Resources of most deposits are mostly in place residuum, but a few are also redeposited lateritic material. Ni-Co laterites occur along the present or paleo- surface above weathered bedrock. WebThe geochemistry and mineral content of the deposit suggest that, as in many other Ni …
