Abstract:Nickel and cobalt were recovered from Ramu laterite type nickel ore with high pressure acid leaching technology. The process introduced in detail includes slurry treatment, high pressure acid leaching (HPAL), cycling leaching and slurry neutralization, CCD countercurrent washing, iron and aluminum removal with neutralization, precipitation of nickel hydroxide and cobalt hydroxide, deep sea tailings placement (DSTP). The problem presented in the process was investigated and improvement measurements were put forward. The recovery rate of nickel and cobalt are ~96% and ~94% respectively.
