【 摘 要 】

The NaCl- KCl system as fused-salt solvent for leaching has shown to have some advantages over traditional solvents. In this work the solubility of copper, nickel and cobalt oxide in this system, as impurities in manganese concentrate, was studied. The euthetic mixture of NaCl - KCl at 700ºC was used at several fusion times and the dissolved metals were determined by Atomic Absorption Spectrometry. The results have shown that in these conditions only copper was solubilized.
