| Abstract: |
| With the depletion of sulfide nickel ores, developing nickel laterite ores in a high efficiency and low cost method is significant to meet the increasing requirement of nickel. The article introduced the status and properties about laterite ore in the world. Meanwhile, this article introduced the present technologies for dealing with nickel-bearing laterite, which contained pyro-metallurgical process, hydro-metallurgical extraction and other technologies. The advantages and disadvantages of these methods are also analyzed. At the same time, it pointed out future developmental direction in hope of providing reference for exploitation of low grade laterite ores. |
