Abstract: A mathematic model for the uncertainty in determining the nickel content in nickel-bearing laterite by flame atomic absorption spectrometric method is established. The relevant uncertainties are classified in terms of components. The uncertainty of each component class, their combination standard uncertainty and expanded uncertainty are computed.

Key words: Nickel-bearing laterite, Nickel content determination, Uncertainty, flame atomic absorption spectrometric method
