Lateritic nickel ore deposits - Wikipedia
Extraction. Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits ). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.
