| Summary: | Toxic metals, which are found in waste sludge from mine tailings of lead and zinc Sase, were immobilized with different compaction imobilazacionim agents (indigenous clay, red mud ) in the monoliths of different proportions. The efficiency of immobilization procedures was monitored using diffusion leaching tests (ANS 16.1). Also, certain parameters (coefficients of diffusion, leachability index) were determined to be used for evaluating the efficiency of immobilization techniques previously applied. In the treatment of tailings with clay and red mud can be observed decrease in mobility of metals (Cr, Ni, As, Pb and Zn) with an increase in the percentage of added red mud, while the Cu and Cd comes to deviations. A mixture of clay tailings and red mud proved to be a very good immobilization agent for all treated metals. |
