• Description:
  This paper describes fundamental research into the equillibrium modeling of the solvent extraction of metals by the Bureau of Mines. As the first part of this research, the extraction of copper from ammoniacal solutions with lix 64n was investigated. The primary goal of this research was to develop a mathematical model that could predict the equillibrium distribution of metal ions to within 5 pct of the actual concentrations. Additional goals of this effort were to develop a model that required only limited initial condition parameters and could accurately predict equillibrium values in practical situations; i.e., relatively high metal loading from high-ionic-strength solutions such as might be obtained in industrial leaching processes.
