Separation of Iron, Nickel, and Cobalt from Sulphated

Abstract A twostage selective precipitation technique was developed for the separation of iron, nickel, and cobalt from sulphated leach liquor of nickeliferous lateritic oxide ore obtained from Sukinda Valley, Orissa, India. In the first stage of precipitation, solid CaCO3 is added to the sulphated solution at 90 to 95176;C till the pH is adjusted in the range of 2.2 to 2.5.
