Advanced study on the extraction of Nickel from its ores
lined autoclaves (all modern plants). Leach temperatures vary in the range of 245 to 270°C. Solid-liquid separation is carried out by Counter-Current Decantation (CCD). There are various ways of purifying the nickel-containing solution and separating nickel and cobalt. In modern plants, such separation is carried out by solvent extraction (SX).
