Abstract
Distribution coefficients measured as Mg 2+, Ca 2+, Ni 2+, Co 2+, Mn 2+ and Cu 2+ co-precipitated with Fe 2+ to form siderite gave values of 1.3 · 10 −3, 0.085, 0.012, 0.83, 6.5 and > 400, respectively. Except for Ni, these data correlate well with carbonate solubility-product data. An estimated distribution coefficient between Mg and Fe in carbonates, based on the solubilities of magnesite and siderite as a function of pH and P CO 2 , has been shown to be near to the measured value. The distribution coefficients have been used to gain a better understanding of the carbonates that are found in the supergene profiles of several Western Australian Ni deposits and they could assist in understanding banded iron-formations.
