Abstract

• Acid mine drainage (AMD) represents a serious environmental problem related to sulfide minerals and coal mining. High content of toxic metals and high acidity in AMD adversely affects surface water, groundwater and soil. The abandoned mine of the Smolník deposit in Slovakia is a typical example in this respect. The quality of AMD needs to be monitored and suitable treatment methods need to be developed. The aim of this paper was to demonstrate the technical feasibility of heavy metals removal from AMD using physical-chemical and biological-chemical methods. The base of the physical-chemical method was electrowinning. The principle of the biological-chemical method was the selective sequential precipitation (SSP) of metals with the application of hydrogen sulfide produced by sulfate-reducing bacteria and sodium hydroxide solution. Both the electrowinning and SSP processes decrease the content of heavy metals in AMD. The pre-treatment of AMD by chemical iron-aluminum precipitation (in the case of electrowinning tests) and chemical iron precipitation (in the case of SSP tests) improved the selectivity of the processes. A further aim of the work was the improvement of the SSP. During the electrochemical experiments, 99% Zn removal - under metallic form - and 94% Mn removal - under MnO2 form - both with a high degree of purity, were achieved. The SSP process reached the selective precipitation of chosen metals with 99% efficiency - Fe, Al and Mn in the form of metal hydroxides, Cu and Zn as metal sulfides. The results achieved may be used for designing a process appropriate for the selective recovery of metals from the AMD discharged from the Smolník deposit. (literal)
