“…Currently, numerous methods such as critical fluid extraction, conversion methods eg. sulfuric acid leaching are used for the recovery of valuable components such as metals (Hamby 1996;Evdokimov and Evdokimov, 2014;Muravyov et al 2014), but they are usually expensive. The problem of sewage sludge/flotation tailing presence is related mainly to their use as landfill (waste and sediments contaminated with heavy metals are collected in the greatest amounts during flotation and extraction of mineral resources) (Macklin et al 2003).…”

The aim of the study was to estimate the ability of ten tree and bush species to tolerate and accumulate Cd, Cu, Pb, Zn, and As species [As(III), As(V), and total organic arsenic] in industrial sewage sludge extremely contaminated with arsenic (almost 27.5 g kg(-1)) in a pot experiment. The premise being that it will then be possible to select the most promising tree/bush species, able to grow in the vicinity of dams where sewage sludge/flotation tailings are used as landfill. Six of the ten tested tree species were able to grow on the sludge. The highest content of total As was observed in Betula pendula roots (30.0 ± 1.3 mg kg(-1) DW), where the dominant As species was the toxic As(V). The highest biomass of Quercus Q1 robur (77.3 § 2.6 g) and Acer platanoides (76.0 § 4.9 g) was observed. A proper planting of selected tree species that are able to thrive on sewage sludge/flotation tailings could be an interesting and promising way to protect dams. By utilizing differences in their root systems and water needs, we will be able to reduce the risk of fatal environmental disasters.

“…These results suggests that in case of high residual Pb and Zn content in low sulfide tailings it is more appropriate to recover these elements (using methods such as flotation) (e.g. Muravyov et al 2014;Shu-juan et al 2014;Navidi Kashani et al 2008) before reutilization and incorporation in mortars. …”

“…We have previously found that the technology of two stage bac terial chemical leaching with acidophilic microor ganisms allows us to transform nonferrous metals from slags and the waste products of their enrichment into solution if iron silicates are dissolved at a minimum; it also solution bioregeneration when the leaching stage is over [2][3][4][5][6]. We used slag and its flotation concentra tion waste as the objects of research.…”

The study concerns the leaching of copper, nickel, and cobalt from metallurgical production slag with trivalent iron sulphates prepared in the process of oxidation of bivalent iron ions with the use of associ ations of acidophilic chemolithotrophic microorganisms. At the same time, copper extraction in the solution reached 91.2%, nickel reached 74.9%, and cobalt reached 90.1%. Copper was extracted by cementation, and nickel as sulphate can be extracted by electrolysis. Associations of microorganisms can then completely bioregenerate the solution obtained after leaching.
