Characterization of Weda Bay nickel laterite ore from ...

The association of fine grained Mg Ni silicates with oxy-hydroxides in laterites and saprolites represents challenges for ore processing, in particular, in nickel enrichment. The Weda Bay nickel deposit in Indonesia is a typical example of these complex ores, where clays such as nontronites develop on polyphase serpentinite as protolith.

1. Introduction - file.scirp.org

Nickel recoveries of only about 65% can be achieved by 825˚C. To achieve recoveries of about 95%, temperatures approaching 1100˚C are required and here the nickel grade is about 50%. The thermodynamic model shows that for the saprolites, the temperature for maximum nickel recovery depends on the amount of NiO in either MgSiO 3 or Mg 2 SiO 4.

Nickel containing sulfide ore deposits are commercially treated in a number of ways. One such way is to produce a flotation concentrate, from which the nickel content is then oxidatively leached. Other processes such as smelting to matte followed by leaching, or direct heap leaching of the ore itself, also produce a nickel containing solution.

Oct 10, 2017· 1. Introduction. Nickel (Ni) is the twenty fourth most common element in the earth's crust; it naturally occurs as sulfides or laterites (oxides) (Crundwell et al., 2011, Kerfoot, 2000).Cobalt occurs in trace amount in laterite ores and it is often extracted as a by-product (Crundwell et al., 2011, Donaldson et al., 1986, Donaldson and Beyersmann, 2000).
