||Adsorption reactions of both single ions and multiple ion mixtures with sulfide minerals (chalcocite, galena, pyrite, and sphalerite) were investigated in the metal concentration range of 0.0001 to 0.00001 M. Chromium (III), iron (III), barium (II), cadmium (II), copper (II), nickel (II), lead (II), zinc (II), silver (I), and arsenic (III) were used in batch-type experiments. Adsorption isotherms were plotted and conformity to both the Langmuir adsorption equation and the linear isotherm was evaluated. Observations were compared with predictions of metal phase distribution/partitioning obtained with the MINTEQA1 equilibrium metal speciation model.
