摘要: Nickel laterite ores account for over 60% of global nickel supply. They are the product intensive deep weathering serpentinites under humid tropical conditions. is concentrated to 1.0 wt% and hosted in a variety secondary oxides, hydrous Mg silicates smectites. The formation, mineralogy grade deposits controlled by interplay lithology, tectonics, climate geomorphology. Most have multi-phase development, evolving as their climatic and/or topographic environment change. richest (>3 Ni) formed where oxide-rich regoliths were uplifted Ni leached downwards concentrate neo-formed saprolite.
