REVIEW OF THE PAST, PRESENT, AND FUTURE OF …

laterites – an oxide ore. Nickel production from sulfide ores is reaching a plateau, and a gradual shift to the exploitation of laterites was a logical development. In the 1950s, approximately 90 % of the nickel was produced from sulfide ores; until 2009, nickel production from laterites increased to 50 % of the global production.
