  • Mechanochemical pre treatment of lateritic nickel ore with

    Basturkcu et al. (2017) applied mechanical activation before leaching of a lateritic nickel ore and found that while an 80% Ni extraction was obtained after 8 h of leaching with the conventionally milled sample, the same Ni extraction percentage could be achieved after 2 h of leaching under the same conditions with the mechanically activated ore.

  • The process design of gold leaching and carbon in pulp

    Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.511 to ensure minimum loss of cyanide as hydrogen cyanide.
