Laterites. Other important classes of ore are the laterites, which are the result of long weathering of peridotite initially containing a small percentage of nickel. Weathering in subtropical climates removes a major portion of the host rock, but the contained nickel dissolves and percolates downward and may reach a concentration sufficiently high to make mining economical.

Abstract Nickel is mostly extracted from sulfide ores, however, laterite ores account for over 60 pct of all nickel resources in the world, and despite its predominance, there is no well-established process to extract nickel from such ores. Nickel in laterites is hosted in many different compounds such as oxides, hydroxides, and silicates minerals. The sulfation-roasting …
