Use of the life cycle assessment and best available technique for ecological evaluation of technological processes in mining and processing of zinc and lead ores in Poland
Use of post-flotation tailings for backfilling the Zn and Pb ore mine excavations was assessed by live cycle anal. (LCA). Uses of mixts. of the post-flotation tailings with fly ash, modified ash, silica binder, cement and gelatinizing agents for backfilling the excavations were compared with the usual sand backfilling by the best available technol. (BAT) method. The highest efficiency showed the process based on the use of fly ashes from a power station.
