Laterites make up over 70 % of both nickel production and known terrestrial resources today and have been the fastest growing source of nickel for some time. In Part 2 of this series on 'Processing nickel' we dig deeper into the specifics of laterites, one of the two main nickel ore types and look at smelting, the most common processing technique.
