The purpose of this study is to propose the flotation procedure seafloor massive sulfide (SMS) ores separate chalcopyrite and galena as froth sphalerite, pyrite, other gangue minerals tailings, which currently facing difficulties due presence water-soluble compounds. obtained SMS ore sample contains CuFeS2, ZnS, FeS2, SiO2, BaSO4 in addition PbS PbSO4 Pb minerals. Soluble compounds releasing Pb...
Decades of mining activity have resulted in the accumulation significant amounts tailings that are deposited over natural vegetation, forming deposits tens meters thick. The poor organic matter and macronutrients contain a high concentration potentially toxic elements (PTE). Their surface remains unvegetated for long periods time is susceptible to fluvial wind erosion. Equisetum arvense E. telm...
Ecological restoration of mine tailings have impact on soil physiochemical properties and microbial communities. The surface soil has been a primary concern in the past decades, however it remains poorly understood about the adaptive response of microbial communities along the profile during ecological restoration of the tailings. In this study, microbial communities along a 60-cm profile were ...
