In the present study it was evaluated the capacity of molasses for removing seven metals (Fe, Zn, Cu, Cd, Cr, Pb, and Ni) from three types of waste: galvanic sludge (pH = 7.1 ? 7.8), mineral residue from a lead metallurgical plant (pH = 5.0 ? 5.8) from Baia Mare (Romania), and tailing pond residue from Aurul - Baia Mare (pH = 2.1 ? 3.0). Several leaching tests were conducted in the laboratory in order to investigate the influence of molasses concentrations (0 %, 1%, 5%, 10%) on heavy metal leaching. It was observe...
