Distribution of Gold and Silver between Copper and Matte S.N. SINHA, H. Y. SOHN, and M. NAGAMORI The distribution coefficients of silver and gold between copper and matte phases have been measured at 1400 and 1500 K. For 0.07 to 0.13 wt pct silver and 0.0022 to 0.0042 wt pct gold in ironfree matte, the distribution coefficients of silver and gold are independent of concentration. For iron-bearing matte, the distribution coefficients of silver and gold are correlated with iron content of the matte. From the measured values of the distributton coefficients of silver and gold, the activity coefficients of AgS05 and Au in copper-saturated matte have been calculated. The following correlations express these results: log Y~gS0_~lll : - 4 2 5 / T - 0 . 0 7 4 + 0.09Nves, log 7~u
