- The paper presents information about the research works in Poland concerning microbiological processes of heavy metals bioleaching from ores, wastes and sewage sludge. Main scientific centers working on biohydrometallurgy, including Warsaw University, Silesian University and Wroclaw University of Technology were taken into account. The basic waste materials applied in biohydrometallurgical processes are lowgrade ores, post-flotation wastes, concentrates and sewage sludge. In Poland the experiments were carried out using copper ores and flotation wastes, arsenic concentrates, magnesite and arsenopyrite wastes, zinc and galena concentrates. The research work covered a bioleaching mechanisms observation, estimation of the process effectiveness as well as the determination of bacterial strains active in the bioleaching process. Some results of biohydrometallurgical studies of other research centers, (University of Opole, University of Warmia and Mazury and Warsaw University of Technology) were also presented. The advantages of biohydrometallurgical methods application, in comparison with conventional methods of metals recycling were pointed out. Recapitulating Polish achievements in the processes of biological regaining of metals from low-grade ores and waste, it should be affirmed, that works in this range, though valuable and carried out on the world level, they were not introduced in the industry. The majority of investigations concerned only laboratory tests in the small scale. They were carried out mainly on flotation wastes from copper mines in Lubin, Polkowice, Rudna and concentrates of galenit, zinc blende and chalcopiryte as well as on loellignite and arsenopyrite - arsenic waste containing gold, and also recently sludge from galvanization. Few investigations on removal of metal from sewage sludge (activated sludge and sludge after methane fermentation) were carried out. Combined biosorption of metals and bioleachinch - as the final stage of elimination of metals from sewage - was also applied in few cases. It seems necessary, so that Poland joins group of countries applying industrial biohydrometallurgical processes, particularly to recovery of copper and zinc and to removal of metals from wastes and sewage sludge
